A Digital Rotor Flux Observer For Robust Vector Control Of The Induction Machine

The aim of this paper is to find a solution for the rotor flux observation problem in an induction machine drive with a robust controller which performs the feedback of the slip frequency. The observer structure shall provide an accurate estimation even in the presence of either rotor resistance variation or load torque disturbances.3107112Hasse, K., On the dynamics of speed control of a static AC drive with a squirrel-cage induction machine (1969), Ph.
