| 摘 要： | 针对永磁同步电动机常规模糊控制的不足,提出了一种基于模糊和预测的自适应控制策略.该策略通过分析模糊控制存在的控制盲区,设计了控制模式切换值,并在速度偏差较大时采用带修正因子的模糊控制,以改善对象在不同情况下的动态响应特性;而当小偏差时采用基于模型的一步预测控制,提高控制精度.仿真结果表明,采用该方法的调速系统具有良好的控制效果.

| Abstract: | In order to tackle the problems existing in conventional fuzzy control method of permanet magnet synchronous motors(PMSMs),an adaptive control strategy based on fuzzy control and predictive control was proposed.The switch value of control modes through the analysis of the control blind area existing in fuzzy control was designed,and the fuzzy control with adjusting factor was adopted when the velocity deviation was larger in order to improve the dynamic response performance of the object in different situat... |
