A method for the deadbeat flux level control of a direct‐field‐oriented induction motor with position control loop has been developed that employs an adaptive rotor flux observer. The observer is a full‐order type and is used not only in the direct‐field‐oriented controller, but also to identify stator and rotor resistances of the motor. The observer reduces the sensitivity of a deadbeat controller to fluctuations in the motor parameters. The main advantage of this method is that it improves the efficiency of an induction motor without sacrificing dynamic performance. This paper describes the method as well as the fundamental characteristics of the system derived from experimental and simulation results.
