In this paper, a controller‐observer scheme, based on passivity feedback equivalence and the sliding mode technique, is designed to achieve rotor velocity and rotor flux norm tracking for the model of an induction motor. The passivity feedback equivalence control law design is based on a passive decomposition property of induction motors recently proposed in the literature and a sliding mode technique that allows to achieve the control objective, even in the presence of bounded parametric uncertainties. An observer is included in the control design to estimate the magnetic fluxes. A complete study of the passivity and stability properties of the resultant closed‐loop system is also made.
