Abstract:To improve the system performance and simplify the control circuit of the high speed switched reluctance motor (SRM), an application specific integrated circuit (ASIC) named SR3P10K07A was designed, which owns proper hardware functions such as the angular position control and so on. Based on ASIC, a digital controller of high speed SRM is developed in this paper. In this controller, some functions can be accomplished by ASIC with high efficiency and strong anti-interference capability, such as rotor position signals processing and control angles calculation. At the same time, the micro control unit (MCU) will be responsible only for the realization of control algorithm and state detection. Therefore, the system can significantly reduce the needs for the resource of MCU, and the single chip microcomputer (SCM) can be used to achieve the real-time control of high speed SRM. Finally, the controller is used in an experiment for the high speed SRM, and the maximum speed of SRM can reach 130 000r/min. Consequently, the results show that it can meet the controlling requirement of high speed SRM effectively.
