Fuzzy Controller for Synchronous Motor

Article Preview

Abstract:

The parameters of PID control couldn’t be adjusted on-line, so it also led to not good precision of velocity. This paper presents the implementation of adaptive fuzzy controller for accurate speed control of a permanent magnet synchronous motor (PMSM). The adaptive fuzzy controls were designed to solve above problems. According to the settling fuzzy rules, the voltage vectors are selected to control the inverter. The zero voltage space vector is used to keep the steady state and reduce frequency of inverter. The simulation results show that the proposed control scheme has stronger robustness and better performance than the conventional control scheme.
