摘　　要：开关磁阻电机(SRM)是一种新型无刷电机,为了实现变开关角控制,现有SRM控制系统多采用DSP或高档单片机,削弱了成本优势。提出一种四相SRM变开通角控制系统,采取只变开通角,不变关断角的控制方式,用8位单片机即可实现。研究单片机的资源分配,实现了软件角度细分方法和变开通角控制方法,最后给出了测试结果。The switched reluctance motor(SRM)is a new brushless motor.In order to achieve variable switch-angle control,the existing SRM control system mostly uses DSP or high-grade MCU,which weakens the cost advantage.A four-phase SRM variable opening-angle control system is presented through an 8-bit MCU,which changes only the opening-angle while remaining the closingangle unchanged.The resource allocation of MCU is studied to achieve the angular fine division by software and the variable opening-angle control.Finally,the test results are given.
