This study focuses on how to prevent a pressure surge form happening in a water hydraulic system. In the water hydraulic system, pressure surge emerging after cavitation invokes a serious damage on water hydraulic devices, and also has undesired influence which might make the system unstable. Both controlling a water hydraulic actuator's motion and suppressing a rapid pressure decrease must be archived simultaneously. However this is not possible to achieve with a conventional water hydraulic system, which has only one degree of freedom in its control. Thus, a new control method using two servo valves is proposed. In this paper, the problem of the conventional water hydraulic system is described and a control method to control two servo valves for the purpose of preventing the pressure surge is discussed. As result, validity of the proposed new control method is proved experimentally.
