Recently, the demand for motion simulators used as testing devices has been increasing. For example, driving simulators is important for the observation and grasp of human's operation characteristic under various run conditions, development of vehicles design, and operation support system. When motion simulators are used as testing devices, the motion simulators cannot obtain the reliable experimental data without the running reproduction performance of real motion. Although, hydraulic servo system is often used for the simulators, the hydraulic system has the fault that acceleration distortion arises by friction between cylinder and piston under conventional displacement proportional control. In this study, control technique that improves acceleration tracking performance is proposed, based on dual model matching, for the hydraulic servo system. Then the effectiveness of the technique is veritied through experiments.
