摘　　要：针对电液伺服系统跟踪控制问题,提出一种基于等价输入的自适应一般模型控制方案。在电液伺服系统存在建模误差、时变参数和不可测扰动的情况下,控制器能够有效地跟踪系统被控参数;且控制器参数整定方便,物理意义明确。通过仿真表明,该控制方法对非线性的电液伺服系统实现自适应控制是正确有效的。Aiming to the tracking control problem of nonlinear electro-hydraulic servo, a design scheme of generic model control based on input equivalent disturbance was presented. The controller can effectively track parameters under control for electro-hydraulic servo systems with modeling errors and time-varying parameters and unmeasurable disturbances. It is very easy to tune for controller whose parameters are of very explicit physic meaning. The simulation results for nonlinear electro-hydraulic servo systems demonstrate the correctness and effectiveness of approach proposed.
