Global Adaptive Observer for a Class of Nonlinear Systems

Overview & Synopsis

The problem considered in this report is the joint estimation of state and some parameters for a class of truly nonlinear systems. The proposed method is constructive and garantees global convergence. It has been inspired by the technique of high gain observer and by a recent result on linear adaptive observer. A numerical example is presented for illustration. Potential applications of the adaptive observer arc adaptive control fault detection and isolation.
