PI and Fuzzy Speed Controllers for PM Synchronous Motor Drive

Abstract

Permanent Magnet Synchronous Motor (PMSM) has been gradually more used in industrial application as a result of a rapid dynamic response and precise control. This paper proposed a high performance Field Oriented Control (FOC), which is a closed loop control to get better dynamic performance of the PMSM in addition to improve accuracy speed control. Two types of controllers are used; the first controller is the Proportional-Integral (PI) and the second controller is a PIcontroller founded on Fuzzy-PI controller in terms of reducing steady state error, rising time, overshoot and smoother speed response. Space Vector Pulse Width Modulation (SVPWM) method is considered according to harmonics result and losses. A MATLAB/SIMULINK program is arranged for simulating the whole drive systems. The simulation results prove the various dynamic operations.

Modeling and simulation of quasi-Z-source indirect matrix converter for permanent magnet synchronous motor drive

“…The vector control theory is used in PMSM drives with d-q reference frame, hence the controlling of flux and torque is achieved independently, so by applying vector control, the PMSM is equivalent to separately excited DC motor operating in steady state [13]. To improve performance of vector control, various controllers are proposed such as traditional Proportional Integral (PI) controller, Proportional Integral Derivative (PID) controller, fuzzy PI controllers and others [14]. PI controller has been widely employed in the industry because of low cost and small steady-state error [15].…”
