Semi-Global Output Consensus for Discrete-Time Switching Networked Systems Subject to Input Saturation and External Disturbances

Abstract

The semi-global output consensus problem for multiagent systems depicted by discrete-time dynamics subject to external disturbances and input saturation over switching networks is investigated in this paper. Assume that only a small part of subsystems have directly received the output of the exosystem. The distributed consensus algorithms are proposed by adopting the low-gain state feedback and the modified algebraic Riccati equation. Then, the outputs of all subsystems can reach synchronization asymptotically with those of the exosystem by using the proposed consensus protocols on some preconditions. Both the connected switching networks and the jointly connected switching networks are considered for the semi-global output consensus problem, respectively. Some numerical simulation results are shown to validate the theoretical analysis.

Formal Specification of Continuum Deformation Coordination

“…ery agent is determined in a centralized fashion. Consensus [5] [14] [7] [3] [19] [1] [36] [15] [28] [34] and containment control are the most common decentralized coordination approaches. Multi-agent coordination using firstorder consensus [16] and second-order consensus [5] [14] has been extensively investigated by researchers in the past.…”

“…Refs. [28] [34] evaluate consensus under a switching communication topology in the presence of disturbances.…”

On Serre Reduction of Multidimensional Systems

“…In general, this involves Serre reduction of multivariate (nD) polynomial matrices to some simple equivalent forms, especially their Smith normal forms. Serre reduction can help to investigate the structural of nD polynomial matrices, which has wide applications in image, complex networked system, and other areas (see [6][7][8][9][10][11]).…”

A New Perspective to Algebraic Characterization on Controllability of Multiagent Systems

“…In recent years, cooperative and coordinated control of networked multiagent systems has become a surge of research activities. e controllability is a basic and important problem in modern control theory, which plays a key role in the analysis and synthesis of networked multiagent systems and has wide applications and advantages in formation control, pinning control, containment control and tracking control, etc [1][2][3][4][5][6][7][8][9][10].…”
