Active flux observer-based high-speed control of a permanent magnet synchronous motor

The goal of this paper is to develop a sensorless algorithm for controlling a permanent magnet synchronous motor (PMSM) at high speeds based on active flux observer. The suitable application is a turbocharger. Many applications are build using a field oriented control based on information provided by a position sensor, but this control present limitations like high sensitivity to parameter variations and slow transient response. A sensorless motion is imposed due to the high speeds operation of the turbocharger where a position sensor will increase the system’s costs plus that and is not feasible. Position sensor will be used only for starting. The simulation results were obtained using MATLAB/Simulink environment. The sensorless operation of the turbocharger at maximum speed is investigated. In this situation, the maximum speed must be reached in the shortest amount of time for the turbocharger to be efficient.
