文章摘要: The design of acceleration servo controller is presented in this paper to improve the control precision of a two-axis vibration table. The degree-of-freedom synthesis and decomposing matrices are obtained based on the geometry relationship of two hydraulic actuators. The three-variable feed-forward controller, which is favorable to improve the stability as well as the system’s damping ratio, is used to extend acceleration frequency band of the system. The input filter is used to achieve acceleration control of the vibration table and a real-time control system of the angle vibration table is developed by using matlab/XPC toolbox. Finally, the effectiveness of the acceleration servo controller was verified by using the experimental results.
