Trang 9The theory of variable structure systems with sliding modes is currently one of the most important research topics within the control engineering domain Moreover, recently a number of important applications of the systems primarily in the fi eld of power electronics, control of electric drives, robotics and position regulation of sophis-ticated mechanical systems have also been reported Therefore, the objective of this monograph is to present the most signifi cant latest developments in the theory and engineering applications of the sliding mode control and to stimulate further research
in this fi eld
The monograph consists of 28 chapters It begins with six contributions devoted to various signifi cant issues in power electronics In the fi rst chapter, Ben Saad et al pro-pose, test and compare sliding mode and fuzzy sliding mode controllers for DC-DC converters In the second chapter, Petkova et al consider the operation of the single-phase inverter and single-phase active power fi lter and prove, both in simulations and laboratory experiments, the eff ectiveness of sliding mode controllers in these two ap-plications Then, Al-Hosani et al also consider the design of DC-DC buck and boost converters They develop the sliding mode approach which implements – very common
in industry – proportional integral derivative (PID) controllers The main idea of that chapter may be summarized as enforcing sliding mode such that the output converter voltage contains proportional, integral and derivative components with the predefi ned coeffi cients Chatt ering is then reduced through the use of multiphase power converter structure The proposed design methods are confi rmed by means of computer simula-tions In the next chapter, Zhu and Kang consider arc welding/cutt ing power supply and propose a “synthetic” sliding mode and PI controller They propose to use the PI controller in the current loop and the sliding mode controller in the voltage loop The results are verifi ed by experiments conducted on a 20 kW arc welding/cutt ing power source They show on one hand good dynamic performance of the system, and on the other decreased undesirable voltage overshoot Another contribution concerned with power electronics is the chapter by Ayad et al which presents sliding mode control of fuel cells, supercapacitors and batt ery hybrid sources for vehicle applications Then, the chapter by Susperregui presents and evaluates fi rst-order and higher-order sensorless sliding mode control algorithms, for a doubly-fed induction generator The algorithms not only aim at governing active and reactive power exchange between the doubly-fed induction generator stator and the grid, but also ensure the synchronization required for smooth connection of the generator stator to the grid
Sliding mode systems are a feasible option not only for power converter control but also for electric drive regulation Therefore an important issue of induction motor control is
Trang 10addressed in the next two chapters The chapter by Cortes-Romero and Sira-Ramirez presents
a combination of two control loops, one employing a discontinuous sliding mode controller and another one based on the combination of generalized proportional integral control and gener-alized proportional integral disturbance observer The authors of the chapter demonstrate – by experiments performed on an actual induction motor test bed with a voltage controlled brake – that the proposed combination results in robust position and tracking control of induction motors In the next chapter, writt en by Reama et al a new simple and easy to implement adap-tive sliding mode scheme for speed and fl ux control of induction motor using online estimation
of the rotor resistance and load torque are proposed The two chapters on control of induction motors are followed by a contribution of Patre and Panchade, which is concerned with a unifi ed sliding mode approach to torque, position, current and speed regulation of DC drives Then the next chapter, by Santo et al., presents the design and implementation of a sliding mode position controller for a linear switched reluctance actuator devoted primarily for robotic applications The section devoted to the problem of electric drive control ends up with a chapter on friction compensation for a mini voice coil motors The chapter writt en by Lin et al., demonstrates that sliding mode control approach may reliably eliminate stick slip oscillations and reduce the steady state error This conclusion is drawn based on experimental results performed on a mini voice coil motor mounted on a compact camera module
The next three chapters are concerned with selected issues in robotics The fi rst of them, ten by Becerra and Sagues proposes a robust controller for image-based visual servoing for diff erential drive mobile robots The second one, by Rivera et al., is devoted to the application
writ-of a higher order, namely super-twisting sliding mode controller for trajectory tracking writ-of an under-actuated manipulator and also for induction motors Then Herman and Kozłowski con-sider rigid, serial manipulators and present an extensive survey of selected non-adaptive slid-ing mode controllers expressed in terms of the inertial quasi-velocities They also point out a number of advantages off ered by sliding mode control schemes using inertial quasi-velocities.The next seven chapters present successful applications of sliding mode control paradigm in other areas than power electronics, electric drives and robotics The section devoted to those applications begins with the chapter by Fung and Chang on sliding mode force and motion control of three very popular mechanisms, i.e slider-crank, quick-return and toggle mecha-nism Then Tournes et al propose a higher order sliding mode control scheme for automatic docking of space vehicles The issue of higher order sliding mode control is also considered in the chapter, by Suares et al In that contribution higher order sliding mode is successfully used
to suppress nonlinear dynamics in physical plants with friction which is inevitable in all chanical systems Higher order sliding mode approach is further considered in the chapter by Salgado-Jiménez et al on control of remotely operated vehicles which are nowadays indispens-able in performing the inspection tasks and maintenance of numerous underwater structures, common in the oil industry, especially in deep and not easily accessible to humans waters That chapter demonstrates that sliding mode control is a viable option for controlling underwater vehicles which operate in a highly dynamic and uncertain environment oft en aff ected by waves and strong currents Another interesting and very well worked out application is described in the next chapter authored by Schindele and Aschemann They propose three types of sliding mode controllers (conventional, second-order and proxy) for a linear axis driven by four pneu-matic muscles and verify performance of these controllers on a laboratory test rig Then Kim et
me-al present adaptive sliding mode controller of adhesion force between the rail and the wheel
in railway rolling stocks The section concerned with various applications of sliding mode trol concludes with the chapter by Wen on optimal fuzzy sliding mode control of biochips and biochemical reactions
Trang 11con-The last section of this monograph presents selected new trends in the theory of sliding mode control It begins with a chapter by Nowacka-Leverton and Bartoszewicz point-ing out some advantages of sliding mode control systems with time-varying switch-ing surfaces Then the chapter by Sato et al discusses a new variable structure design method which results in good transient performance of the controlled system and small steady state error The next chapter by Chen and Tseng is devoted to the att enu-ation of an important and fairly undesirable eff ect of chatt ering The authors present a new controller design procedure aimed at chatt ering reduction by low-pass fi ltering of the control signal Also the subsequent chapter, writt en by Mihoub et al., considers the chatt ering phenomenon It effi ciently combines multi-model approach to the reaching phase performance improvement with the second order sliding mode controller design for discrete time systems Another signifi cant theoretical issue is considered by Adloo
et al Those authors propose sliding mode controller for two dimensional (2-D) systems and discuss the switching surface design and the control law derivation In the penul-timate chapter of this monograph, Yasser et al propose to incorporate some elements
of artifi cial intelligence, namely appropriately trained neural networks, into the sliding mode control framework and demonstrate the advantages of this approach Finally, the last chapter of this book – writt en by Nied and de Oliveira – also concentrates on some aspects of combining neural networks with sliding mode control, however their goal is quite diff erent from that of Yasser et al Indeed Nied and de Oliveira present a sliding mode based algorithm for on-line training of artifi cial neural networks, rather than exploiting neural networks in variable structure controller construction
In conclusion, the main objective of this book was to present a broad range of well worked out, recent application studies as well as theoretical contributions in the fi eld
of sliding mode control The editor believes, that thanks to the authors, reviewers and the editorial staff of Intech Open Access Publisher this ambitious objective has been successfully accomplished It is hoped that the result of this joint eff ort will be of true interest to the control community working on various aspects of non-linear control sys-tems, and in particular those working in the variable structure systems community

1 Introduction
Switched mode DC-DC converters are electronic circuits which convert a voltage from one level to a higher or lower one They are considered to be the most advantageous supply tools for feeding some electronic systems in comparison with linear power supplies which are simple and have a low cost However, they are inefficient as they convert the dropped voltage into heat dissipation The switched-mode DC-DC converters are more and more used in some electronic devices such as DC-drive systems, electric traction, electric vehicles, machine tools, distributed power supply systems and embedded systems to extend battery life by minimizing power consumption (Rashid, 2001)
There are several topologies of DC-DC converters which can be classified into non-isolated and isolated topologies The principle non-isolated structures of the DC-DC converters are the Buck, the Buck Boost, the Boost and the Cuk converters The isolated topologies are used
in applications where isolation is necessary between the input and the load The isolation is insured by the use of an isolating transformer
The DC-DC converters are designed to work in open-loop mode However, these kinds of converters are nonlinear This nonlinearity is due to the switch and the converter component characteristics
For some applications, the DC-DC converters must provide a regulated output voltage with low ripple rate In addition, the converter must be robust against load or input voltage variations and converter parametric uncertainties Thus, for such case the regulation of the output voltage must be performed in a closed loop control mode Proportional Integral and hysteretic control are the most used closed loop control solutions of DC-DC converters This can be explained by the fact that these control techniques are not complicated and can be easily implemented on electronic circuit devises
Nowadays, the control systems such as microcontrollers and programmable logic devises are sophisticated and allow the implementation of complex and time consuming control techniques
The control theory provides several control solutions which can be classified into conventional and non-conventional controls Many conventional controls, such as the PID control, were applied to DC-DC converters The design of the linear controller is based on the linearized converter model around an equilibrium point near which the controller gives

This chapter aims to compare SMC and FSMC of DC-DC converters The average models of Buck, Boost and Buck Boost converters are presented in section 2 Then in section 3, some classical sliding mode controls are presented and tested by simulations for the case of Buck and Buck Boost converters In order to improve the DC-DC converters robustness against load and input voltage variations and to overcome the chattering problem, two approaches
of FSMC are presented in section 4
Let us consider a switching converter which has two working topologies during a period T
When the switches are closed, the converter model is linear The state-space equations of the circuit can be written and noted as follows (Middlebrook & Cuk, 1976):
From the equation (1) and (2) we can determine the averaged model given by equation (3)
for an entire switching cycle T

and x , y and u are respectively the average of x, y and u during the switching period T
Let us consider the Buck, Boost and Buck-Boost converters presented by Fig 1, Fig 2 and
Fig 3 respectively The state space representation can be expressed for these converters as
follows :

expression of these matrixes for the considered converters
