Faults Estimation and Decentralized Control for a Networked Control System with Specified Faulty Actuators

Ching-Min Lee
Abstract—In this paper, we investigate a problem related to an estimation and decentralized control for faults for a networked control system whose configuration between subsystems is with variable structures. Taking advantage of the variable structures, the NCS could be formulated as a distributed type or a decentralized one, or as a time-varying kind switching between these two types. In the NCS, subsystems subject to network induced phenomena, such as networked induced time-varying delay, packets losses, and some faults caused by faulty actuators. To deal with these considerations, we introduce a fault dynamics and derive a set of LMI-based delay-dependent conditions for a stability analysis problem to the corresponding augmented estimation system for faults. Based on the resultant stability conditions, we also derive a set of LMI-based synthesis conditions for designing estimators and decentralized controllers to cope with faults. At the end of this paper, a numerical example is presented to show the feasibility and efficiency for the proposed method.

Index Terms—Decentralized control, faults estimation, LMI, NCS.
