In this research, the positioning control of water hydraulic servo cylinder system with the simple adaptive control (SAC) is discussed. Conventional model reference adaptive control (MRAC) also achieves good tracking performance for cylinder control, but the controller structure was much complicated and was not easy to be realized in application. Compared with MRAC, SAC has simpler and lower order structure, i.e., has higher feasibility. But only few papers concerning with the application of the control performance of SAC to hydraulics and pneumatics are available, especially for water hydraulics. In this paper, we will examine and evaluate the control performance of the SAC strategy and it is confirmed that SAC gives better tracking performance compared with PI control.
