In the paper a variable structure control (VSC) has been proposed and applied to the position control of a water hydraulic rotary actuator. Based on the model of the water hydraulic vane actuator, the simulation experiments with VSC controller are done and compared with PID controller. Simulation experiment results show that in position control applications, the use of VSC as the controller of the system can improve the dynamical and static state performances of the system. Especially, the VSC system provides higher-precision position as well as stronger robustness to parameters varieties than the PID control system. Also, the chattering has been effectively controlled and reduced in the VSC application by adding a boundary layer. The position control properties of the water hydraulic rotary actuator validate the effectiveness of the proposed VSC method.

“…The effects of the friction force and leakage are more serious problem to obtain a high control performance for a water hydraulic motor than for a water hydraulic cylinder. Although a PCM [3] or a simple gain scheduling method [4] were applied to this system, an accurate control performance is not obtained so far.…”

With the recent increased concerns for global environmental problems, the water hydraulic technique using pure tap water as a pressure medium has become a new drive source comparable to electric, oil hydraulic and pneumatic drive systems. However, the main problems for precise control in a water hydraulic servo motor system are steady state errors and overshoot due to its large friction torque in the low velocity range of a motor. In this research, the sliding mode control combined with the disturbance observer is applied to control the rotational angle of a water hydraulic servo motor. We examined the rotational angle control performances with these methods for load fluctuations.

“…Water as a pressure medium gives many benefits compared to mineral oil, including easy maintenance, good availability and so forth. In [1], [2], the position displacement and velocity control of water hydraulic cylinder are realized introducing the profile generator which generates smooth control signal to attenuate a large overshoot. The rotational angle control and the speed control of water hydraulic servomotor are also tested with conventional PID controller in [3].…”

Water hydraulic servo system is attractive technology for safety environment. This paper presents a design method of a robust rotational velocity controller of water hydraulic servomotor for the uncertain parameters and the load fluctuation. To overcome the highly nonlinearity of flow equation, we linearize and parametrize it. Considering the effect of uncertain parameter perturbation, e.g. load fluctuation and friction parameters, a method of Lyapunovbased recursive design is applied to construct a robust rotational velocity controller. Simulation results demonstrate the proposed robust controller provides better disturbance rejection and dynamic properties than those achieved by a conventional PID controller.
