Abstract :
This paper presents a closed loop vector control of permanent magnet synchronous motor (PMSM) AC servo system with improved current and speed controller. The effective current and speed controller are designed based on integral separation strategy and fuzzy-PI double mode control strategy. A performance comparison of the proposed PMSM drive system with conventional PI controller based drive system is provided in simulation and experiment. Comparative simulation and experimental results demonstrate the better dynamic responses in both current and speed for the proposed fuzzy control based PMSM drive system.
