| Abstract |
The permanent magnet synchronous motor (PMSM) has numerous advantages over other machines that are conventionally used for AC servo drives. Sinusoidal PMSM drives are capable of achieving high performance servo control. Additionally, they may allow high speed operation range using vector control techniques. The control techniques are used to extract the high efficiency operation and extremely fast dynamic response which are inherent characteristics of well designed PMSM machines. In order to assure high performances and robustness of the PMSM drives, hysteresis and PWM currents regulators are used to ensure that the actual currents flowing into the motor are as close as possible to the sinusoidal reference. In this paper, a description, analyse and evaluation of the use of hysteresis current controllers when used in PMSM fed by two and three levels inverter are presented. The effects of changing the magnitude of the hysteresis window on the motor torque pulsation, the inverter switching frequency and drive performances are also examined by predicting accurately the stator current wave, resulting torque pulsation and speed response. |
