MODELING AND SIMULATION OF SENSORLESS CONTROL OF PMSM WITH LUENBERGER ROTOR POSITION OBSERVER AND SUI PID CONTROLLER

Abstract

This paper presents an investigation and
evaluation of the performance of the surface Permanent
Magnet Synchronous Motor drive under the Simplified
Universal Intelligent PID controller (SUI PID). The
estimation of the rotor position and the speed in dynamic
rate were derived by the use of the Luenberger state
observer for currents and MRAS (Model Reference
Adaptive System) observer. It is also shown how to use a
Luenberger state observer in a flux oriented control
(FOC) scheme to implement a sensorless vector control
strategy. The mathematical descriptions of the system
and simulation results were obtained in this paper.
