摘　　要：针对液压电梯的非线性数学模型,直接用机理建模非常困难,得不到可用于控制的数学模型。因此采用辨识方法建立模型。其次,设计了PID控制器,理论上推导了液压电梯速度反馈控制系统的传递函数,并给出了PID控制参数的取值范围。最后,建立了液压电梯的Simulink模型,验证了PID控制算法的有效性和可行性。According to the nonlinear mathematical model of hydraulic elevator,it was very difficult to use mechanism model directly,and cannot get the controlling mathematical model. Therefore,identification method was used to set up the model.Secondly,the PID controller was designed,and the transfer function for the speed feedback control system of hydraulic elevator was theoretically deduced,and the value range of the PID controller parameters was given. Finally,the Simulink model of hydraulic elevator was established,and the effectiveness and feasibility of PID control algorithm were verified.
