摘　　要：为提高永磁同步电机双闭环调速系统响应速度与抗干扰性,给出一种依据内模控制及有功阻尼概念的PMSM双闭环调速系统控制器设计方法.通过建模分析对PI+前馈解耦电流环控制器进行优化,依据内模原理设计出带有箝位积分法抗击分饱和的电流内环解耦控制器.在此基础上,构造有功阻尼代替自然阻尼,利用转速环频带带宽对PI调节器参数进行整定.通过计算机仿真验证,对比传统FOC控制下的调速系统,使用本文所设计的控制器可提升系统响应速度,降低系统超调量,仿真结果表明该方法的有效性.In order to improve the response speed and anti-interference of PMSM double closed loop speed control system, a method of controller design was proposed for PMSM double closed loop speed control system based on internal model control and active power damping concept. The PI+ feed-forward decoupled current loop controller is optimized through modeling and analysis. According to the internal model principle, a current inner loop decoupling controller with clamped integral method to resist sub-saturation is designed. Then, the active damping is constructed instead of natural damping, and the PI regulator parameters are tuned by using the speed loop bandwidth. Through computer simulation and comparison with the traditional FOC speed control system, the controller designed method can improve the system response speed and reduce the system overshoot, and the simulation results show that the method is effective.
