摘　　要：为解决垂直升降抢修塔液压控制系统的位移控制精度及低速稳定性要求,文中采用粒子群PID控制器对电磁阀控液压缸位置进行控制。此外,设计了垂直升降抢修塔的液压控制系统,建立了AMESim-Simulink联合仿真模型。通过粒子群算法对PID参数进行优化,并对传统PID与粒子群PID控制系统进行仿真试验对比。仿真结果表明:相较于传统PID,基于粒子群PID控制系统中活塞杆运行速度变化更为平稳、无振荡,稳定时间缩短4 s,稳定速度提高了10%,该控制方式能更好地满足抢修塔控制系统的位移控制精度及低速稳定性要求。In this article,in order to ensure the accuracy in displacement control and meet the low-speed stability requirements of the vertical lifting repair tower’s hydraulic control system,the particle swarm PID controller is used to control the position of the solenoid valve-controlled hydraulic cylinder.The hydraulic control system of the vertical lifting repair tower is designed,and the AMESim-Simulink co-simulation model is set up.The PID parameters are optimized with the help of the particle swarm algorithm,and the simulation experiments are carried out to compare the traditional PID and particle swarm PID control systems.The results show that compared with that of the traditional PID,the piston rod’s running speed in the particle swarm PID control system changes more smoothly without oscillation;the stabilization time is shortened by 4 s,and the stabilization speed increases by 10%.This method better satisfies the accuracy in displacement control and meets the low-speed stability requirements of the repair tower’s control system.
