We propose a nonlinear feedback controller that can control the induction motors which have been applied to many electrical facilities with high dynamic performance by means of decoupling of moor speed and rotor flux. The nonlinear feedback controller needs the information on some motor parameters. Among them, rotor resistance varies greatly with machine temperature. Anew recursive adaptation algorithm for rotor resistance which can e applied to our nonlinear feedback controller is also presented in this paper. To demonstrate the practical significance of our results, we present some experimental results.
