【Abstract】 Changes in trajectory will lead to changes in the control model of the electric suspension system,thus limiting the train speed. To solve the problem,firstly,the concept of equivalent acceleration and its measurement method are introduced. Secondly,the dynamic equation of magnetic levitation system based on Halbach array is established,and its stability is analyzed by analytic method. In order to unify the suspension control model,an improved feedback linearization control method is proposed.The proposed control method can not only improve the stability of the system,but also can improve the anti-jamming ability of the system through real-time monitoring and compensation of the system interference. Finally,the effectiveness of the control method is validated by simulation analysis.更多还原
