Abstract

In this paper we study the fault tolerant control (FTC) problem on wireless networked control system (WNCS) which consists of N coupling sub-systems. We aim at finding a FTC scheme which makes the WNCS satisfy a quadratic cost function. Since in the actual control process, the system state and fault may physically unmeasurable, an estimation scheme is proposed to estimate the system state and fault simultaneously. Finally, a numerical example is presented to demonstrate the effectiveness of the proposed method.
