摘要
针对开关磁阻电机低速运行状态下转矩脉动大的问题,分析单神经元PID原理和开关磁阻电机特性,采用微分先行代替原有的微分,并且引入模糊控制对微分先行单神经元PID的输出增益调节以获得较好的控制性能,提出了模糊—微分先行单神经元PID控制器。将设计的模糊—微分先行单神经元PID控制器用于开关磁阻电机的直接瞬时转矩控制,并与基于单神经元PID的开关磁阻电机直接瞬时转矩控制进行仿真比较。仿真结果表明,所提出方法有效地减小了开关磁阻电机的转矩脉动,且系统动态性能良好。
For the problem of switched reluctance motor with large torque ripple in low speed operation, the fuzzy-differential prior single neuron PID controller is proposed in this paper. By analysing single neuron PID and switched reluctance motor characteristics, the original differential was replaced by differential prior, and the fuzzy control was introduced to adjust gain of differential prior single neuron PID in order to obtain better control performance. The design of fuzzy-differential prior single neuron PID controller for switched reluctance motor direct instantaneous torque control was compared with the direct instantaneous torque control of switched reluctance motor based on single neuron PID control simulation. Simulation results show that the proposed control strategy effectively reduces the torque ripple of switched reluctance motor and has good dynamic system performance.
