platform to design and prototype controllers in simulation and implement them

in real-world systems using a unified software architecture that easily takes

students from the simulation environment and with a toggle switch on the

LabVIEW front panel to deploy their controller to the physical hardware

• Products: CompactRIO, LabVIEW Real-Time Module, FPGA Module,

MathScript RT Module, Control Design and Simulation Module, LabVIEW

“Overall, the LabVIEW framework gave students the freedom to take greater control of the hardware controller design process.” - Professor Jonathan How - Massachusetts Institute of Technology
