摘　　要：无刷直流电机调速系统转速环通常采用PI控制器,为了克服PI控制器输出的饱和非线性影响,设计一种变结构anti-windup PI控制器,给出了系统的稳定性条件。当控制器输出处于饱和区时,将转速误差与积分器输出之差反馈到积分环节输入端,使积分器输出迅速收敛,控制器快速退出饱和区。为验证变结构anti-windup PI控制器的可行性,通过仿真实验,结果表明采用变结构anti-windup PI控制器的无刷直流电机调速系统能有效抑制饱和现象,改善系统的动静态性能。PI controller is usually used in the speed loop of BLDCM speed control system.In order to overcome the saturation nonlinear effect of PI controller,a variable structure anti-windup PI controller is designed and the stability conditions is given to the system.When the controller is saturated,the difference between the speed error and the integrator output is fed back to the input of the integral link,so that the integrator output converges quickly and the controller exits the saturation quickly.The feasibility of the variable structure anti-windup PI controller is verified by the simulation experiment.The results show that the speed control system of BLDCM with the variable structure anti-windup PI controller can effectively suppress the windup phenomenon and improve the dynamic and static performance of the system.
