Fractional Order PI Controller Based PMSM Drive under Dynamic Loading Conditions


  • Department of Electrical Engineering, RCET, Bhilai - 490024, Chhattisgarh, India


Objective: The main objective of this paper is to examine the permanent magnet synchronous motor (PMSM) drive using controller under dynamics. Statistical Analysis: The method adapted for analyzing dynamics occurring in PMSM drive is fractional calculus on PI (proportional-integral) controller. The vector control scheme was applied for speed control and stimulated in MATLAB and Simulink under various operating conditions. Findings: The FOPI controlled drive shows better control execution property and robustness over traditional integer order PI controller. The dynamics during load and speed variations are figured out to be normal than the actual case by use of FOPI as speed controller. Improvement: The stimulation result shows the performance and adequacy of the proposed FOPI controlled PMSM drive system.
