Abstract :

In this paper, the driver with antiwindup and fuzzy high-performance and robust PI controller has been suggested for Permanent Magnet Synchronous Motor (PMSM). This controller is suggested for the design of the robust driver for three phase PMSM and the cost reduction of its control system. It’s useful for the industrial application and automation and ultimately speed control and the improvement of the dynamic behavior of the PMSM. Antiwindup control strategy prevents the increase of the output beyond its saturation point. So, it avoids the saturation. In effect, the suggestion of this new speed control scheme is in line with a goal to realize a better antiwindup scheme. The simulation results are shown for PMSM for two cases of antiwindup control strategy and fuzzy control strategy and with different operation modes. For this purpose, different three phase PMSM output waveforms are presented. These waveforms are presented for fuzzy control strategy in constant torque, constant speed and different reference speeds with focus on speed curve, electromagnetic torque and phase currents.
