| 摘 要： | 本文采用了直接瞬时转矩控制(DITC)方法来抑制开关磁阻电机的转矩脉动。介绍了DITC方法的控制原理,据此设计了不同导通区间内的转矩滞环控制器,采用BP神经网络自适应PID控制器调节静差。仿真结果表明,采用BP-PID的DITC方法能够很好的抑制转矩脉动,系统响应时间短,控制精度高,转矩波形明显优于传统电流斩波控制下的转矩波形,证明了本文所设计的DITC方法能够有效地提升开关磁阻电机动静态工作过程中的转矩性能。

| Abstract: | This paper adopted Direct Instantaneous Torque Control(DITC) method to reduce the torque ripple of switched reluctance motor.The control principle of DITC was described,and used this principle,a hysteresis torque controller for different conduction areas was designed,using BP neural network adaptive PID control to adjust the static error.Simulation results that used DITC which controller is BP-PID controller can effectively reduce SRM torque ripple,system response time is short,and it has high control preci... |
