Abstract
This paper studies the performance of the direct torque control of the permanent magnet synchronous motor drive. Direct torque control has several advantages such as simplicity, fast transient response, less parameter dependence, and absence of rotor position sensor. However, the high torque and flux ripples are considered the main drawback of the classical direct torque control especially at low speed. The torque and flux hystersis controllers are considered the main sources of these ripples. In this paper, a novel fuzzy logic direct torque controller is proposed to enhance the performance of the classical direct torque control. The hystersis controllers and lookup table are replaced by the proposed controller. Fuzzy controller determines the switching states for the inverter from the torque and flux errors and flux position angle. The proposed scheme still has the all advantages of the classical direct torque control. No additional measurements or control loops are required. Simulation works have carried out to evaluate the performance of the proposed fuzzy logic direct torque controller scheme. The waveforms of the torque, flux and speed of the classical direct torque control are compared to those obtained from the proposed scheme.
