Based on the complex quantity state space descriptions of an induction motor, firstly the least squares parameter identification algorithm for an induction motor when its speed is constant is discussed, the sensitivity of this algorithm for the speed fluctuation is showed. Secondly by using the real parameter complex variable error model and its parameter adjusting algorithms developed in this paper, some new parameter identification methods that can be used in the variant speed driving condition are proposed. These identification methods can be used for parameter adaptive problem of an AC driver control system.
