摘要：

This paper deals with a robust motion control of a low-pressure water hydraulic cylinder under non-linear friction. In order to ensure good tracking performance as well as to guarantee robustness, the sliding mode tracking control is utilized in combination with a non-linear friction compensator. Application of the scheme to a low-pressure water hydraulic cylinder position control has led to a significant reduction in tracking error when compared with the perfect tracking control scheme.
