摘　　要：针对非线性的电液伺服系统,提出一种利用基于输入等价干扰的通用模型控制算法(ICMC)来设计控制器新策略。该控制器用估计得到的输入等价干扰及时进行自适应前馈补偿。控制器参数整定方便,物理意义明确。ICMC控制器能有效地跟踪液压伺服系统的时变参数和不可测扰动,通过仿真实验表明,该控制方法对非线性的液压弯辊力系统实现自适应控制是正确有效的。A new scheme of using common model control based on input equivalent disturbance （ICMC） to design controller was presented for nonlinear electro-hydraulic servo control systems. The controller may ac- quire adaptive feed-forward compensation based on input equivalent disturbance. It is very easy to tune for the controller whose parameters are of very explicit physic meaning. The influence on control performance of the time-varying parameters and unmeasurable disturbances can be effectively compensated. The simulation results for nonlinear hydraulic bending system are given to demonstrate the correctness and effectiveness of the ap- proach proposed.
