Abstract

A variable structure controller (VSC) is proposed for direct torque and stator flux linkage control of an interior permanent magnet (IPM) synchronous motor. In comparison with conventional direct torque control (DTC), the inverter switching frequency of the proposed drive is constant and controllable by using space vector modulation (SVM), the torque and flux ripple are significantly reduced. The fast response and robustness merits of DTC are preserved.
