Design of Fault-Tolerant MIMO System From LQR Theory
-
Abstract: In this paper a new design procedure is proposed. This procedure can lead to a stable fault-tolerant MIMO system from LQR theory. It is shown that, in the sense of system stability, a state feedback MIMO system capable of tolerating either the actuator or the sensor failure or even both can grow out of modification of the quadratic weights in the LQ cost function. Such a modification procedure is given for the design of a stable fault-tolerant MIMO system.
