A stablizable method for uncertain linear systems with actuator failures

This article studies the redundancy problem of an uncertain linear system with partial actuator failures from the viewpoint of sabilizability and controllability. It transforms the uncertainty and partial actuator failures into a math model, and presents the distance between a controllable certain system and instablizable uncertain system, both of which with actuator failures. An example demonstrates the validity of the method proposed.
