Pmsm Control System Research Based on Vector Control

With The development of power electronic technology, microelectronic technology and modem motor control theory, synchronous motor speed control systems are widely used. PMSM plays an important role in AC servo system. Its control strategy research attracts more attention. The speed control system model performance is introduced and introduces the principles of SVPWM(Space Vector Pulse Width Modulation) and CHBPWM (Current Hysteresis Band PWM). Simulation models of PMSM servo system based on SVPWM and CHBPWM are built in MATLAB/SIMULI K, and simulation results are analyzed.
