A Vector-Control System Based on Fuzzy Self-Tuning PID Controller for PMSM

Abstract

The permanent magnet synchronous motor (PMSM) is increasingly playing an important role in alternating current(AC) transmission system. Recently, lots of researches have been investigated for the PMSM system without speed and position sensors. The Vector-control system based on fuzzy self-tuning PID is proposed in this paper. The new algorithm based on fuzzy self-tuning PID can improve the performance of the system. The speed and torque fluctuations are reduced. Simulation results show that the validity of the proposed strategy.
