Controllability of Directed Heterogeneous Networked MIMO Systems

This paper studies the controllability of networked multi-input-multi-output (MIMO) systems, in which the network topology is weighted and directed, and the nodes are heterogeneous higher-dimensional

Controllability of Directed Networked MIMO Systems With Heterogeneous Dynamics

It is found that a network of heterogeneous systems can be controllable even if the underlying network topology is uncontrollable, and unravels another fundamental property that affects the network controllability—the heterogeneity of the node dynamics.

Controllability of heterogeneous networked MIMO systems

This study investigates the controllability of weighted and directed networks of multi-input-multi-output (MIMO) systems, in which the nodes obey heterogeneous linear time-invariant (LTI) dynamics, and derives a necessary and sufficient controllable condition for the heterogeneous networked system.

Controllability of networked higher-dimensional systems with one-dimensional communication

In this paper, the state controllability of networked higher-dimensional linear time-invariant dynamical systems is considered, where communications are performed through one-dimensional connections and it is shown that uncontrollable node systems can be assembled to a controllable networked system, while controlling node systems may lead to uncontrolled systems even for the cycle topology.

Controllability and observability of networked singular systems

It is shown that the controllability of the overall system is an integrated result of the network topology, the subsystem dynamics, the external inputs, and the inner interactions, which indicate that the observability ofthe whole system depends only on the parameters of its subsystem.

It is revealed that heterogenous networked systems under some assumptions can be separated into several independent subnetworks, such that the controllability of the whole system is equal to the controlling of each subnetwork.

A promising point of the structure analysis taken in this paper is that, it can handle certain subsystem heterogeneities, which are illustrated by some practical systems, including the liquid-level systems, the power networks and the mechanical systems.

In this article, the notion of pinning control for directed networks of dynamical systems is introduced, where the nodes could be either single-input single-output (SISO) or multi-input multi-output

Pinning control and controllability of complex dynamical networks

The controllability of a special temporally switching directed network of linear time-varying node systems will be addressed, leaving some more general networks and challenging issues to the end for research outlook.

Controllability of Weighted and Directed Networks with Nonidentical Node Dynamics

The concept of controllability from control theory is applied to weighted and directed networks with heterogenous linear or linearized node dynamics subject to exogenous inputs, where the nodes are

Nodal Dynamics, Not Degree Distributions, Determine the Structural Controllability of Complex Networks

It is argued that more important than issues of structural controllability are the questions of whether a system is almost uncontrollable, whether it is almost unobservable, and whether it possesses almost pole-zero cancellations.

Optimizing controllability of complex networks by minimum structural perturbations.

This work proposes a general approach to optimizing the controllability of complex networks by judiciously perturbing the network structure by validated theoretically and demonstrated numerically for homogeneous and heterogeneous random networks and for different types of real networks as well.

Network controllability is determined by the density of low in-degree and out-degree nodes.

It is shown that the density of nodes with in degree and out degree equal to one and two determines the number of driver nodes in the network, and an algorithm is proposed to improve the controllability of networks.

Graph-theoretic approach to controllability and localizability of decentralized control systems

The controllability and the localizability problems are considered under the decentralized information structure using some concepts from graph theory. First of all, the information structure graph

Controllability of diffusively-coupled multi-agent systems with general and distance regular coupling topologies

This paper studies the controllability of linearly diffusively coupled multi-agent systems when some agents, called leaders, are under the influence of external control inputs. We bound the system's

Controllability of complex networks

Analytical tools are developed to study the controllability of an arbitrary complex directed network, identifying the set of driver nodes with time-dependent control that can guide the system’s entire dynamics.

Controllability analysis of multi-agent systems with directed and weighted interconnection

This article employs weight-balanced partition to classify the interconnection graphs, and considers the effect of the zero row-sum restrictions of the system matrices on structural controllability.
