Abstract: Based on a slot-less tubular permanent magnet synchronous linear motor (TPMSLM), the disturbance suppression method was studied. To improve the accuracy of analysis and simulation, a novel model, which takes the asymmetry of the three-phase inductance into account, was derived. A new disturbance suppression structure was introduced. Considering cases of the disturbance and the actual control process of the motor system, the effects of the new structure were studied. The structure was split and the disturbance suppression effects of the two sub-structures were studied respectively, which further illustrated the control characteristics and feasibility of the introduced structure. Experiments were carried out on a TPMSLM. The performance of the whole system was tested and compared with the conventional method. The effectiveness of the new structure was verified.
