摘　　要：针对某泵控缸电液位置伺服系统的特点,提出了自抗扰控制方案。自抗扰控制器的设计不依赖于被控对象的精确数学模型,并可将对象的不确定性、未建模动态和外界干扰的总量都估计出来,使系统性能得到有效补偿。仿真结果表明,该方案能保证系统具有响应快、无超调、稳态精度高的特点,并且对内、外扰动具有较强的抑制能力。An active disturbances rejection control approach is proposed to control the electro-hydraulic position servo system of the pump-controlled cylinder. The design of active disturbances rejection controller is independent of the object＇ s accurate mathematic model, and the controller can estimate total disturbances including parametric uncertainties, un-modeled dynamics and external disturbances, then compensates it to the servo system. The simulation results show that the system have advantages of speedy response, no overshoot, high accuracy and strong robustness against modeling uncertainty and external disturbance.
