A fuzzy logic controller based vector control of IPMSM drives

Abstract EN

This paper explores a fuzzy-logic based speed controller of an interior permanent magnet synchronous motor (IPMSM) drive based on vector control.

PI controllers were mostly used in a speed control loop based field oriented control of an IPMSM.

The fundamentals of fuzzy logic algorithms as related to drive control applications are illustrated.

A complete comparison between two tuning algorithms of the classical PI controller and the fuzzy PI controller is explained.

A simplified fuzzy logic controller (FLC) for the IPMSM drive has been found to maintain high performance standards with a much simpler and less computation implementation.

The Matlab simulink results have been given for different mechanical operating conditions.

The simulated results confirmed that the FLC-PI has a lower ripple than the conventional PI controller.
