Fuzzy-PI controller applied to PMSM speed controller: Design and experimental evaluation

Abstract

Several advantageous are offered by synchronous motors with a permanent magnet (PMSM) which are required in numerous fields for high-performance 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.
