摘　　要：针对传统单自由度PI控制系统难以兼顾抗扰特性和跟踪特性的缺陷,设计了一种基于误差判断的二自由度控制器并给出了参数整定方法。首先,通过简化电流环的数学模型得到转速环的控制目标;然后,采用多主导极点配置法和时域响应性能指标分别设计出二自由度控制器的PI参数;最后,在Simulink平台上搭建了仿真模型并采用基于模型设计(MBD)方式生成嵌入式代码。实验结果验证了所提出的二自由度控制方法的可行性和有效性。Aiming at the defects of traditional single degree-of-freedom PI control system that it is difficult to take into account both anti-interference characteristics and tracking characteristics,a two degree-of-freedom(2 DOF)controller based on error judgment was designed and a parameter tuning method was given. Firstly,by simplifying the mathematical model of the current loop,the control target of the speed loop was obtained,and then the PI parameters of the 2 DOF controller were designed using the multiple dominant poleplacement method and the time domain response performance index. Finally,the simulation model was built on the Simulink platform and the embedded code was generated by using model-based design(MBD)method. The experimental results verify the feasibility and effectiveness of the proposed 2 DOF control method.
