摘要：
Taking the high-speed maglev train as the research object，the vehicle-guideway coupling vibration was discussed under the condition of elastic track. The minimum suspension element model of the actual vehicle-guideway coupling was established，and the mechanism analysis of the stability and coupling vibration of the open-loop system was conducted. In order to make up for the lack of effective information utilization of proportional-integral-differential（PID）controller，a full-state feedback controller was designed based on pre-compensation. By analyzing the effect of the feedback gain matrix on the system tracking performance and vibration suppression capability through simulation，an idea was proposed to appropriately reduce the suspension clearance in exchange for the improvement of vibration suppression capability. Further，the influence law of the feedback coefficient on the performance of the suspension system was analyzed， and on this basis an optimized pre-compensation full-state feedback control framework was obtained. Through experiments，the full-state feedback control was demonstrated based on pre-compensation，which can effectively suppress the elastic coupling vibration of the guideway. © 2023 Science Press.
