Abstract

This paper aims to implement a sensorless vector-control system with an efficient speed-estimation procedure for the induction motor (IM) drives with the promising split-source inverter (SSI) configuration. A simplified observation method of the rotor-speed signal is proposed with the principles of the indirect scheme of field orientation (IRFOC) and based on the relations of phase axes for the adopted motor. The main contribution of this paper is to effectively estimate the rotor position of the machine with a direct estimation without any need for PI controller in the position observer procedure. Moreover, the estimated speed signal is obtained with a simplified method without any need for additional observers to detect the speed from the estimated position signal. To assure the observability of the proposed sensorless speed-control system, a complete analysis supported with the test results under the normal operation are realized. The obtained analysis assures the proposed sensorless control strategy's efficacy with the split-source inverter compared to the conventional inverter topology.
