Improved speed control using Anti-Windup PI controller for Direct Torque Control based on permanent magnet synchronous motor

摘要

This paper present a PI with Anti-Windup (PI+AW) strategy to regulate a rotor speed of permanent magnet synchronous motor (PMSM). The strategy and PMSM modeling are based on Direct Torque Control (DTC) with a Space Vector Modulation (SVM). A Matlab/Simulink is used to establish the simulation model. As the result of simulation, Overshoot of a starting torque and a setting time of rotor speed are reduced. Consequently, the PI+AW are significantly greater than conventional PI.
