High-Speed Induction Motor State Observer Based on an Extended Kalman Filter

This article deal with the developing of a high-speed electric generator based on the induction motor with massive rotor. The displacement current in a massive magnetic core has a significant impact on the characteristics of this electric machine that is why the state observer must adapt to the rapidly changing of the control object parameters. For this purpose we proposed to use the state observer based on the extended Kalman filter developed on the basis of the induction electric machine equations. The processes modeling in the system of a high-speed electric generator and a state observer were made to verify the taken decisions. The mathematical model of an induction electric machine with a massive rotor and three circuits on the rotor was developed. The simulation results confirmed the correctness of chosen approach.
