Fuzzy Logic Vector Control of PMSM with Speed and Rotor Position Estimation using a Blind Technique based on EKF

摘要

In this paper the speed, rotor position, direct and quadrature axis currents and voltages of a Permanent magnet synchronous motor (PMSM) is estimated using an Extended Kalman filter from the measurements of three phase stator currents only which makes the approach different from the previous similar other works. Then a conventional fuzzy logic controller is implemented to demonstrate the vector control operation of the sensorless PMSM. The proposed fuzzy logic sensor less controller is implemented in real time in a MATLAB/SIMULINK enviournment.
