Abstract

The combination of decentralized and networked control where control loops are closed through a network is defined as Decentralized Networked Control System (DNCS). In this paper, we introduce a general framework that converts a generic decentralized control configuration of non-networked systems to the general setup of Networked Control Systems (NCS). An observer-based decentralized control method is used to illustrate the applicability of the proposed framework. First, a method for designing decentralized observer-based controllers for non-networked systems is discussed. Second, we introduce the general framework that maps the non-networked decentralized control scheme to the networked one. Third, we provide two methods to analyze the closed-loop system stability, given the proposed model. Stability perturbation bounds of the DNCS are derived. Finally, example and simulation results are shown and discussed.
