摘要
电液力控制系统是一个高度非线性而且参数不确定的非线性时变系统,传统的PID控制策略难以取得让人满意的结果。为了使电液力控制系统拥有较好的控制效果,文中提出迭代学习控制策略。采用开环PD的控制策略设计控制器,最后通过Matlab软件对其进行仿真,仿真结果表明,该控制策略可以提高系统的控制精度,提升系统的响应速度。
The electro-hydraulic system is a system which consists of some characteristics, such as strong nonlinear, uncertain parameters and time varying. The conventional PID control method is difficult to obtain satisfactory effect. In order to make the electro, hydraulic system have better control effect, an iterative learning control strategy is proposed in this paper. The article takes control strategy of open loop PD to design controller and uses Matlab to simulate it. The results show that the strategy can improve the control accuracy and the system＇s response speed.
