摘　　要：介绍了采用两个三级同步液压缸驱动的电梯液压系统的设计,运用拓扑原理构建该液压系统的数学模型并对其进行仿真,得到各级液压缸的速度曲线和位移曲线,采用PID控制器对液压系统进行控制,仿真结果表明:采用PID控制的电梯液压系统稳定性高,具有良好的工作性能。The design of elevator hydraulic system employing two level three synchronous hydraulic cylinder drives was intro-duced. The mathematical model of the hydraulic system by using the topological principle was constructed and it was simulated. The velocity curve and displacement curve of each hydraulic cylinder were gotten, and the proportional integration and differential （PID） controller was used to control the hydraulic system. The simulation results show that： the stability of hydraulic elevator PID control sys-tem and working performance are good.
