Abstract Depending on the different design of the reference model, various kinds of Model Reference Adaptive Controller (MRAC)-Based online rotor time constant estimation algorithms have been proposed. The effect of detuned T_r on the flux orientation, electromagnetic torque and reactive power was presented in detail. Then a unified MRAC-based adaptive scheme for online T_r estimation was derived through Lyapunov theorem,which means different MRAC can be obtained with different configuration parameters in the unified scheme. The unified adaptive scheme supplies the theoretical basis for further study of the T_r updating model. Meanwhile, the unified scheme helps improve the system of the algorithms for T_r estimation based on MRAC, providing guideline for the selection of the estimation model. Simulation and experimental results have confirmed the validity of the proposed analysis.

Key words： Induction motor rotor time constant unified adaptive scheme Lyapunov theorem
