Abstract :
For the control of hybrid maglev systems with permanent magnets and electromagnets, differential geometry is introduced to linearize the suspension system by feedback linearization technique, which can guarantee global stability of the system. Considering that in physical systems the suspensions load can changes largely, an improved strategy is proposed based on the typical feedback linearization technique to improve the adaptability of the system to the variation in load. Finally, the effectiveness of the proposed algorithm is evaluated by simulation.
