摘　　要：文章针对阀控液压马达动态特性进行研究,建立液压阀流量方程、液压马达流量连续性方程和液压马达与负载的力矩平衡方程,推导出阀控液压马达的传递函数。运用MATLAB软件的SIMULINK模块对阀控液压马达系统进行动态特性仿真分析。仿真结果表明,在不同负载作用的情况下,系统中加入PID控制和未加PID控制比较,系统的调整幅度和调整时间均减小,PID控制器能够提高系统的抗负载扰动性能。Aiming at the dynamic characteristics of hydraulic valve-controlled motor is studied in this paper,build up the flow equation ofhydraulic valve、flow continuous equation of motor and torque balance equation of hydraulic motor and load,transmission function is derivedfor the hydraulic valve-control motor.The SIMULINK module of MATLAB software is used to simulation the dynamic characteristicsof hydraulic valve-controlled motor system.Simulation results show,in different load conditions,comparison PID control and no PID controlin the system,the adjustment range and time of system are both reduced,PID controller can improve the system performance of restrainload disturbance.
