This paper deals with the observation and control of a class of nonlinear systems. A cascade observer for a class of state affine nonlinear systems is proposed. Considering an output feedback tracking controller, a stability analysis of the resulting closed-loop system is given. The proposed observed- based controller is then shown to be closed loop stable and is applied to an induction motor industrial setup to show the proposed methodology.
Keywords: Induction motor, nonlinear control, nonlinear observer
