Reliable redundant control for nonlinear uncertain systems

This paper is concerned with the reliable control problem of the nonlinear systems that experience the single fault. By using strictly redundant control elements, the methods to design reliable controller are presented. The resulting closed-loop nonlinear systems are reliable in the sense that they provide guaranteed local stability and H_∞ performance not only when all sensors and actuators are operational, but also when any one, but only one, sensor or actuator experiences fault.
