Abstract:

This paper presents the integration of high frequency signal injection (HFSI) and extended electromotive force (EMF) based techniques for sensorless control of permanent magnet synchronous machines (PMSM) intended for propulsion in hybrid/electric vehicles (HEV/EV). Taking advantage of the strengths of each method and thanks to the saliency properties of the machine the operation in the whole speed range is possible. The both sensorless techniques are combined by means of a weighting function to avoid bumps during speed transitions. The performance of the proposed sensorless control strategy in all speed regions and under speed reversal conditions is evaluated through simulations developed in MATLAB®-SimPowerSystems™. The results show that by using the proposed strategy the torque-speed curve for a 50 KW PMSM machine is achieved.
