Abstract

The variation of rotor resistance affects the estimation of flux greatly in vector control system for induction motor

which restricts the operation performance of the system.Real-time identification of the rotor resistance can improve overall system performance.Based on MRAS theory

a new rotor resistance identification algorithm is proposed and the stability of the system is proved by the meaning of Lyapunov.Simulation results show that the method can accurately identify the rotor resistance and has certain robustness.
