Abstract :
An improved direct torque control (IDTC) method is studied in the paper for permanent magnet synchronous machine drive. Conventional direct torque control (CDTC) features a high dynamic response with notable drawbacks such as high torque and flux ripples, variable switching frequency along with acoustic noise. To avoid the shortcoming, an improved method is employed to control the combination of flux and torque. Simulation results are presented to validate the effectiveness of the proposed schemes in this paper.
