Abstract：To solve the problem of the performance degradation due to parameter variations in the vector control of an induction machine, this paper presents a new method of designing adaptive rotor flux observers under the rotor reference frame. Different from previous methods, this method needs no parameter values of an induction machine. The stability and convergence of the algorithms are guaranteed by the parameter adaptive algorithm with a strictly positive real error transfer function. The effectiveness is verified by numerical simulation results.
