Hyperstable MRAS Vector Control of Induction Motor Using Counter-EMF

역기전력 추정방식에 의한 유도전동기의 Hyperstable MRAS 벡터제어

In this paper, describes a rotor speed identification method of induction motor based on the theory of counter EMF MRAS. This method eliminated the pure integrator and we can be expected to rapid responsibility of the speed identification. Therefore, we may improve the initial condition of the integrator and drift problem. The stability of speed estimator is proved on the basis of hyperstability theory. In order to confirm the performance of the proposed system, simulation and experiment is performed.
