摘　　要：传统双缸直顶式液压电梯采用比例调速阀来实现双缸同步控制,其同步精度易受偏载的影响,提出一种位移偏差–电反馈PID闭环控制策略,以提高系统的同步控制性能。利用AMESim仿真软件建立系统仿真模型,并进行对比仿真分析。仿真结果表明:所提出的位移偏差–电反馈PID闭环控制策略能使系统在偏载工况下,精确控制比例调速阀输出流量来跟随位移偏差的变化,提高了系统的同步精度。Since the traditional double-cylinder straight top hydraulic elevator adopts proportional speed control valve to realize the synchronous control of the double-cylinder,its synchronization accuracy is easily affected by the offset load.To improve the synchronous control performance of the system,a closed-loop control strategy of displacement deviation and electrical feedback PID is proposed.The AMESim simulation software is used to establish the system simulation model,and the comparative test is carried out.The simulation results show that the proposed closed-loop control strategy of displacement deviation-electric feedback PID can accurately control the output flow of proportional speed regulating valve to follow the change of displacement deviation under the condition of partial load,and improve the synchronization accuracy of the system.
