Stabilization of nonlinear systems by dynamic feedback

In this paper, the bounded input-bounded output stabilization for nonlinear systems whose states are not available for measurement is studied by using the converse Lyapunov technique. It is found that the introduction of a state detector in the feedback control loop will not cause a significant change in the stability of the system if the initial point of the state detector is accurate enough. A feedback control scheme for achieving BIBO stability is presented.<
