摘　　要：直线感应电机(LIM)有噪音低、振动小、反应速度快等优点,在城市轨道交通应用中日益普及,但LIM边端效应的存在及载荷变化会产生电磁扰动和负载扰动,导致速度跟踪效果不理想。针对上述问题,提出一种基于改进粒子群算法(Improved Particle Swarm Optimization,IPSO)的线性自抗扰(LADRC)速度调节器。首先建立考虑边端效应的电机等效电路模型,在此基础上,通过速度微分方程分析扰动对速度跟踪的影响机理。其次设计LADRC调节器,针对调节器参数难整定的制约问题,采用IPSO算法进行参数寻优。最后,在Matlab/Simulink仿真环境下搭建矢量控制系统。仿真结果表明,相比于其他两种调节器(PID、常规LADRC),IPSO-LADRC能够节省手动调参时间,且在速度突变、负载突变等工况下具有抗扰能力强、动态性能好等显著优势。Linear induction motor(LIM)has the advantages of low noise,low vibration,fast response speed and so on.It is increasingly popular in urban rail transit applications.However,the existence of LIM edge effect and load change will produce electromagnetic disturbance and load disturbance,resulting in unsatisfactory speed tracking effect.To solve the above problems,a linear active disturbance rejection(LADRC)speed regulator based on Improved Particle Swarm Optimization(IPSO)was proposed.First,the equivalent circuit model of the motor considering the edge effect was established.On this basis,the influence mechanism of disturbance on speed tracking was analyzed through the speed differential equation.Secondly,the LADRC regulator was designed.Aiming at the constraint problem that the regulator parameters are difficult to set,the parameters of the regulator were optimized by ipso algorithm.Finally,the vector control system was built in the Matlab/Simulink simulation environment.The simulation results show that compared with the other two regulators(PID and conventional LADRC),ipso-ladrc can save the time of manual parameter adjustment,and has significant advantages such as strong anti-interference ability and good dynamic performance under sudden changes in speed and load.
