... accordance with the simulation result obtained in Fig. 8. Since only the torque is controlled without speed control, the time range of control system under transient state is selected short. The motor ... various cases with and without stator flux control, switch states 1 and 2, respectively in order to demonstrate the validity of the proposed four-switch DTC of a BLDC motor drive scheme with two-phase ... incremental encoder with 2048 pulses/revolution), therefore a good torque estimation can be obtained in (1). C. Torque Control Strategies of the Uncontrolled Phase-c For direct torque control, Fig....
