基于Halbach永磁阵列的直线电机解耦控制方法建模分析

In this paper, one magnetically levitated liner motor with Halbach permanent magnet array is introduced. The magnetic flux intensity model of permanent magnet array and the electromagnetic force and torque model are established. Because the conventional dq0 transform can\'t completely eliminate the torque segments, the direct decoupling method of the coil as an independent driving unit is studied. In order to avoid the end effect of the magnetic flux density, the control method of coils is analyzed. The models of different control algorithm are established and verified by simulation. The suitable control method is established.
