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-dimensionalâ€¦

### Controllability of Directed Networked MIMO Systems With Heterogeneous Dynamics

- MathematicsIEEE Transactions on Control of Network Systems
- 2020

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 controllabilityâ€”the heterogeneity of the node dynamics.

### Controllability of heterogeneous networked MIMO systems

- Mathematics2017 International Workshop on Complex Systems and Networks (IWCSN)
- 2017

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

- MathematicsPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2017

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

- MathematicsIET Control Theory & Applications
- 2019

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.

### Controllability Analysis for a Networked Dynamic System With Autonomous Subsystems

- MathematicsIEEE Transactions on Automatic Control
- 2017

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.

### Structural Controllability of Networked Relative Coupling Systems under Fixed and Switching Topologies

- MathematicsArXiv

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.

### Pinning control and controllability of complex dynamical networks

- MathematicsInternational Journal of Automation and Computing
- 2016

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-outputâ€¦
