基于电磁阀的三轴气浮平台控制研究OA

Space missions are often accompanied by high costs and great risks.Therefore,the precise control of the ground simulation system is of great significance to the on-orbit state verification of the spacecraft.Taking the three-degree-of-freedom micro-low gravity air floating platform driven by solenoid valve as the research object,the theoretical model of solenoid valve is proposed from three aspects:structure,mathematics and energy loss.Then,according to the structural characteristics and parameters of the solenoid valve,a multi-voltage driving control strategy is proposed,and compared with the traditional driving mode.The results show that the multi-voltage drive control strategy can effectively improve the dynamic response characteristics of the solenoid valve and improve the frequency response capability of the solenoid valve.In addition,the lateral,rotational and planar motion control experiments are designed to verify that the solenoid valve based on the multi-voltage drive control strategy can control the air floating platform to obtain the ideal motion trajectory.
