Position tracking control of two permanent magnet linear synchronous motors

With the merits of a simple mechanical structure, high thrust density, quick response, permanent magnetic linear synchronous motor (PWLSM) is widely utilized in automatic processing and assembling industry. On the basis of the fact that modern manufacturing usually requires multiple actuators operating together to complete some complicated tasks, this paper discusses about a position tracking control strategy for the two-PMLSM-based motion control system. The system is constructed to verify the presented strategy. Experimental results indicate that the dynamic error values between two motor falls into 0.17mm.
