Virtual Instrument based fuzzy control system for PMLSM drive

A virtual instrument (VI) based fuzzy control system for permanent magnet linear synchronous motor (PMLSM) drive is presented in this paper. Mathematic model of the PMLSM is presented and the stepper drive scheme is used in the position loop of PMLSM drive. To improve the performance of PMLSM drive, a LabVIEW based fuzzy controller (FC) is proposed for the position loop of PMLSM drive to deal with the dynamic uncertainty and external load effect. Simulation results demonstrated the feasibility of proposed approach.
