On the Design of Reliable Control Systems

This paper presents preliminary results on the design of reliable control systems characterized by open-loop stable controllers, and capable of withstading the outage of any sensor in a predefined subset or of any actuator in a predefined subset of control loops. The approach is based on the relationship between the existence of solutions to an algebraic Riccati inequality and the existence of stabilizing, H
