Summary: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., 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 examined and evaluated the control performance of the SAC strategy and then it was confirmed that SAC gave better tracking performance compared with PI control and showed almost same control performance compared with MRAC.
