Abstract: Several advantageous are offered by synchronous motors with a permanent magnet (PMSM) which are required in numerous fields for highperformance adjustable speed operation. However, PMSMs speed control is related directly to controllers and it needs to be adjusted using an appropriate regulator. In this paper, a proportional integral (PI) regulator applied for PMSM speed adjusting is considered and enhanced using a fuzzy logic process by making PI regulator gains self-adapting and ensures a good performance of the controller in transient states. A PMSM motor controlled using an eZdsp F28335 board is exploited to validate MATLAB/SIMULINK software results, and to show fuzzy-PI improvement and performance under many constraints.

Keywords: fuzzy-PI regulator; permanent magnet synchronous motor; PI controller; speed control.
