介绍了一类电液位置伺服系统的迭代学习控制方法。根据系统的实际输出与理想输出间的误差，以某种学习机理对系统的实际输入不断进行修正，直至实际输出与期望输出间的误差达到满意为止。实验结果表明：只要合理选择学习机理，便可对电液位置伺服系统实现有效控制。 An iterative learning control method for a class of electro-hydraulic position servo system is introduced. According to the error between the actual output and the ideal output of the system, the actual input of the system is constantly amended with some learning mechanism until the error between the actual output and the desired output is satisfied. The experimental results show that as long as the learning mechanism is reasonably selected, the electro-hydraulic position servo system can be effectively controlled.
