Abstract

An induction motor is basically a nonlinear system having three inputs three outputs and in this paper, first, we show that an induction motor can be exactly linearized and decoupled. However, there is the problem that this general exact linearization system is sensitive for parameter variation. So we cope with this problem by using information that is included in approximated linearization system around an equilibrium point. Second, we design an H controller in consideration of parameter variations for exact linearization system. We verify the validity of our proposed design method with respect to both nonlinearity and parameter variation by simulations.
