Abstract :
A novel control scheme for nonlinear multi-input multi-output (MIMO) systems which have unstable zero dynamics is presented. The proposed approach consists of a state-feedback controller which simultaneously achieves the input-output linearization of the nonlinear system and stabilizes the internal dynamics using a Lyapunov-based scheme. The approach is used to design a nonlinear MIMO voltage and speed regulator for a single machine infinite bus power system
