Full fuzzy-logic-based vector control for permanent magnet synchronous motor

摘要

A full fuzzy-logic-based vector control for a permanent-magnet synchronous motor(PMSM) was proposed. The high-performance of the proposed fuzzy logic control(FLC)-based PMSM drive were investigated and compared to those obtained from the conventional proportional-integral(PI) controller at different conditions such as step change in command speed and load, etc. In the simulation and experimental results, the fuzzy-logic controller was employed in the speed and current controller. The comparative experimental results show that the FLC is more robust and, hence, found to be a suitable replacement of the conventional PI controller for the high-performance drive system.
