Abstract

This paper is concerned with the synthesis of a state feedback control system which possesses integrity. System integrity in multivariable control systems is defined as the property that the overall closed-loop system remains asymptotically stable in the presence of a failure in the feedback loop. A state feedback control law which retains asymptotic stability against arbitrary actuator or sensor failure is derived using a positive semidefinite solution of a type of matrix equation. Moreover, the design of large-scale systems against the sensor failures is discussed. The effectiveness of the method is demonstrated with two numerical examples
