Abstract
Sensorless PMSM control algorithms are interested in developing in order to improve operational efficiency and reduce installation space. Many sensorless control methods have been proposed, with numerous significant results have been obtained in recent years. Sensorless control methods mainly compare the actual value with the estimated input current on the stator windings as to adjust the rotor speed. Chattering is inevitable and degrades PMSM speed control quality with respect to being used for closed-loop control loops. This study proposes an advanced Fuzzy Model Reference Adaptive System (Fuzzy MRAS) algorithm to control PMSM rotor speed combined with an angular position estimator to minimize the chattering phenomenon. Proposed fuzzy MRAS algorithm can minimize chattering by allowing error removal between actual and calculated stator currents, thereby improving the quality of rotor speed regulation. The superiority of proposed control method is demonstrated via compared with conventional MRAS and fuzzy control techniques through simulation PMSM speed models using MatLab/Simulink software.
