Fault-Tolerant Control Design for a Class of Linear Systems under the Constrained Communications

Abstract In this paper, the fault-tolerant controller design and the communication data rate are integrally investigated for a class of linear systems with the constrained communication channels. To guarantee the feasibility of proposed fault-tolerant control method, the necessary conditions for the faulty plant and the minimum data rate of the communication are analyzed. Taken into account the communication errors, the adaptive techniques based fault-tolerant controller is constructed to make the faulty system stable. Finally, an example of three-tank system is used to show the efficiency of the proposed method.
