SVM-Based Optimizing Control of Two-Phase Winding Segmented Permanent Magnet Linear Synchronous Motor

This paper presents a space vector modulation (SVM) technique for a two-phase winding segmented permanent magnet linear synchronous motor (WS-PMLSM). First, the advantages of the two-phase WS-PMLSM are discussed, the parameters related to the WS-PMLSM mathematical model are analyzed, and the SVM is applied to the implementation of the WS-PMLSM two-phase sinusoidal voltage inverter. Next, a feedforward implementation method is proposed considering the regularity characteristics of the mover cross-zone operation. Finally, in order to improve the smoothness of operation, an optimal calculation of the current values of each section according to the coverage is proposed, and an optimal control method is implemented by establishing an optimal efficiency model. The experimental results prove the effectiveness of the proposed method.
