Abstract 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.
