摘　　要：根据开关磁阻电机的特性,建立电机数学模型,分析了电机工作原理及电机运行中的相电流、磁链和位置角三者之间的关系;在Matlab/Simulink环境下搭建开关磁阻电机调速系统模型,仿真分析了电压、开断角对电机转速、转矩、电流的影响;基于仿真分析,设计了电流、转速双闭环调速控制系统,并将其与电流斩波调速控制系统进行对比,仿真结果表明,电流、转速双闭环调速控制具有起动快、脉动小和运行稳定等优点,更适用于开关磁阻电机的调速控制。Considered the characteristics of switched reluctance motors, the mathematical model of motors was established. The theory of motor working and the relationship among phase current, flux and position angle was analyzed. In the Matlab/Simulink, the model of switched reluctance motor drive system was built. And the influence that voltage and breaking angle affect the motor speed, torque, current was analyzed. The system of current and speed double loop was established based on the simulation analysis, and comparing with current chopper speed control system. Simulation results show the current and speed double loop system has advantages, such as rapid start, small ripple and stability, which is more suitable for controlling the speed of the switched reluctance motor.
