摘　　要：针对电液伺服控制系统容易受到参数扰动和外部干扰的影响,提出一种积分滑模控制方法。并用极点配置法设计滑模超平面,保证系统的动态品质。仿真结果表明,在电液伺服系统出现参数变化和外部扰动时,积分滑模控制系统有很高的动态性能,抗干扰能力好,具有很强的鲁棒性。A design method of integral sliding mode control is proposed for electrohydraulic servo system which easily affected by parameter variations and external disturbances.The sliding mode hyperplane was designed by using the method of pole assignment,and dynamic-state quality of the control system was guaranteed.The simulation results show that the integral sliding mode control has good dynamic-state performance and high robustness under parameter variations and external disturbances appeared within the electrohydraulic servo system.
