Abstract :
This paper presents a systematic robust controller design for a synchronous reluctance drive system. This robust controller consists of two parts: a forward-loop H∞ controller to improve the transient response; and a load compensator to reduce the load disturbance. Based on a simplified model of the drive system, the robust control algorithm can be derived. The effect of the parameter variations is also studied. A digital signal processor is used to implement the control algorithm. All the control loops are executed by the digital signal processor. The hardware, therefore, is very simple. The drive system performs well. For speed control, the system can be operated even at a low speed as 1 RPM. Several experimental waveforms validate the theoretical analysis
