Fuzzy embedded PI control algorithm and angle experiments of switched reluctance machine

In recent years, switched reluctance motor (SRM) as a rapidly developed new motor has been widely applied in various fields such as household appliances, electric vehicles, aviation industry; its construction is rugged and simple. In this paper, the controller was designed and correlative experiments were made. First the hardware design and software design of the controller were introduced. The core circuit of controller was based on the MCU MC9S12DG128, and the control algorithm was analyzed. Then the speed experiment under different control algorithm was made. The current waveform and speed waveform of the experiment were gathered and analyzed. The results of experiments show that the designed control algorithm meet the system performance requirements. The angle experiments was well analyzed and can be referred by the future works.
