摘  要:
针对非对称缸液压伺服系统的不确定性,非线性和常规PID控制器的缺点,设计了改进的滑模控制器,有效减小了液压位置伺服系统中由于元件参数变化等引起的超调和振荡。利用AMESim/Simulink进行联合仿真,模拟实际工作中电液伺服位置控制系统常常遇到的负载变化、受外力扰动等情况,验证在此环境下控制器对电液伺服位置控制系统的控制效果,以及所设计的滑模控制器的鲁棒性、可靠性。

摘  要:
For uncertainty of asymmetric cylinder of the hydraulic servo system,nonlinearity and shortcomings of conventional PID controller,an improved sliding mode controller is designed,which effectively reduces overshoot and oscillations caused by changes of element parameters of the hydraulic position servo system.Using AMESim/Simulink,we simulated work load change,external disturbance and so on that are often encountered by the hydraulic servo position control system,verified the control effect of the controller on the electro-hydraulic servo position control system under this environment,and robustness and reliability of the designed sliding mode controller.
