One of the main challenging issues in induction motor drives is the lack of knowledge about the actual values of some critical parameters, such as rotor and stator resistances which are subject to large variations during operation. Such problem is difficult to resolve due to the strong interconnection between states and parameters in the nonlinear motor model, besides the unavailability of both rotor...
The aim of this paper is to design an output feedback predictive controller for a class of uniformly observable nonlinear systems. More specifically, our proposal is addressed to the admissible tracking problem for minimum phase nonlinear processes. The unavailable state variables of the system are recovered by using a high gain observer (HGO), before adopting a mild change of coordinate in order...
