摘　　要：开关磁阻电机运行中转矩脉动比较明显,由此引起的电机噪声及转矩波动制约了其在高性能控制领域的应用。优化电机的结构设计及采用合适的控制技术是抑制开关磁阻电机转矩脉动的2种主要方法。在对开关磁阻电机转矩脉动产生机理分析的基础上,从控制的角度综述了开关磁阻电机转矩脉动抑制的若干解决方案的要点,分析了各种控制方法的优缺点,从而对进一步研究提出建议。Certain disadvantages of the switched reluctance motor are that it produces high torque ripple, mechanical vibrations and acoustic noise. The excessive torque ripple has limited their applications in high performance applications. There are two approaches followed for torque ripple minimization. One is improving the structure design of the motor while the other is use of electronic control techniques. An extensive review of the control approaches adopted for torque ripple minimization was presented based on the origin of torque ripple, and their merits and drawbacks were analyzed,and proposed ideas for their future research.
