Abstract

The aim of this work is to build an efficient speed estimate method and a sensorless vector control system for an induction motor (IM) using a promised split-source inverter (SSI) configuration. A more straightforward method for tracking the rotor speed signal based on the motor's phase-axis relationship is derived in detail and processed with a regulated modified space-vector PWM (RMSPWM) technique. The adopted sensorless control system-based SSI is subjected to extensive analysis to ensure its observability, and the findings are corroborated by standard functional test results and parameter adjustments. Moreover, the experimental implementation of the designed SSI prototype is discussed and investigated. The results show the effectiveness of the proposed speed estimation method with the suggested RMSPWM scheme for SSI and its observability and robustness when compared to the conventional modulation topologies.
