Due to the strong nonlinearity of the magnetic levitation mobile platform,all kinds of intelligent algorithms can only locate and move the magnetic levitation mobile platform,and cannot make the mover of the magnetic levitation mobile platform reach the predetermined position along the expected trajectory.In order to solve the problem of trajectory tracking of magnetic levitation mobile platform movers and its accuracy,the differential flatness theory was combined with the control of the magnetic levitation mobile platform.Maglev mobile platform system is a differential flatness system,and the differential flatness theory has its particularity,which can convert a strong nonlinear system into a linear system for control.The mathematical model of the maglev mobile platform was built and simulated in MATLAB/Simulink.The results show that the maglev mobile platform with differential flatness control can make its movers move according to the expected trajectory with higher accuracy,stronger tracking and practicability.
