A Globally Convergent Adaptive Indirect Field-Oriented Torque Controller for Induction Motors
Résumé
One of the most challenging problems in AC drives applications is the design of a simple plug-in adaptation scheme to estimate the unknown rotor resistance and load torque for the industry-standard indirect field oriented control. In this paper we give the first globally convergent solution to this problem for torque control of current-fed induction motors that does not rely on any excitation assumption. Some results on speed regulation are also presented.
