Abstract :
In this paper a flexible direct torque control (DTC) of a sensorless interior permanent magnet synchronous motor drive is proposed based on variable structure approach and space vector modulation technique. According to this method, a sliding mode plus-PI controller is designed for torque and flux control respectively in stator flux reference frame. Simulation results obtained indicate improved performances for the proposed DTC controller and its robustness are preserved for the IPMSM drive.
