Abstract

Due to attractive features such as low cost and highly robust, the demand for Switched Reluctance Motors has reached an all-time high. However, the torque ripple caused by the inherent double salient structure of SRMs leads to speed ripple as well. In order to cope with the aforementioned torque/speed ripple problem, many studies rely on sophisticated control techniques. However, in most of the previous studies the powerful Digital-Signal-Processor is used to realize these sophisticated control schemes since their complicated structures require massive computing power. The fact that the DSP-based solution is not cost effective results in a conflict with the original benefits of SRMs. To cope with the aforementioned problems, this paper employs a variable gain PI-type controller to suppress the torque ripples of SRMs. In order to have a cost effective solution, all the motor drive algorithms and control schemes are implemented using a low cost microcontroller in this paper. Experimental results show that the torque ripple has been significantly reduced so as to verify the effectiveness of the proposed control approach.
