摘　　要：针对永磁同步电机采用传统滑模控制时,响应慢、超调量大、抗干扰能力差等问题,提出了协调控制策略。在传统指数滑模的基础上,设计了可变趋近律的改进滑模算法,与自抗扰控制构建了协调控制策略。利用模糊控制得到可变控制因子,调整自抗扰在系统中的占比。搭建仿真与实物实验平台进行实验,结果表明:该协调控制策略明显提升了系统响应速度,实现了无超调跟踪,增强了系统抗干扰能力。To solve the problems of slow response,large overshoot,and poor anti-disturbance ability of permanent magnet synchronous motor(PMSM)with traditional sliding mode control,a coordinated con-trol strategy was proposed in this paper.Based on the traditional exponential sliding mode,an improved sliding mode algorithm with a variable reaching law was designed,and a coordinated control strategy was constructed in combination with active disturbance rejection control.A variable control factor was obtained by using fuzzy control to adjust the proportion of active disturbance rejection in the system.A simulation and physical experiment platform was built for experiments.The experimental results show that the response speed of the system is significantly improved by the coordinated control strategy,the tracking without overshoot is realized,and the anti-disturbance ability of the system is enhanced.
