Full Fuzzy-Logic-Based Vector Control for Permanent Magnet Synchronous Motors

摘要

This paper proposes a full fuzzy-logic-based vector control for a permanent-magnet synchronous motor (PMSM). The high-performance of the proposed fuzzy logic control (FLC)-based PMSM drive are investigated and compared with the conventional proportional-integral (PI) controller at different conditions, such as step change in command speed and load, and etc. In the experimental results, the FLC is 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.
