Shanling Dong, Enjun Liu, Bo Wang, Meiqin Liu, więcej

International Journal of Robust and Nonlinear Control > 34 > 13 > 8902 - 8918

The article deals with the security control stabilization problem of uncertain Markov jump power systems with input dead zone under stochastic denial‐of‐service (DoS) attack. DoS attack is modeled as a discrete‐time Markov process. Dual hidden Markov models are respectively used to detect the modes of the original power systems and the one under DoS attack. Based on the detected modes and neural networks...

Distributed formation control of networked mobile robots from the Udwadia–Kalaba approach

Pengfei Liu, Yuqing Hao, Qingyun Wang, Guanrong Chen

International Journal of Robust and Nonlinear Control > 33 > 18 > 11518 - 11537

In this article, formation control of networked mobile robots is studied. Two control strategies for the leaderless case and the leader‐following case are developed from the Udwadia–Kalaba approach, respectively. Differing from the existing results about formation control, which focus on kinematic models of robots, this article considers dynamic models and obtained a lower‐cost control force. To improve...

Asian Journal of Control > 25 > 2 > 695 - 709

In this paper, we study the secure consensus problem for multiple‐input‐multiple‐output (MIMO) linear multi‐agent systems (MASs) subject to denial‐of‐service (DoS) attacks, where an attack on an agent will block its associated communication channels until it stops. Firstly, we design an unknown input observer (UIO), based upon which we develop a resilient consensus controller, where the UIO depends...

Mathematical Methods in the Applied Sciences > 45 > 17 > 10640 - 10658

In this paper, a pinning control scheme for adaptive trajectory tracking of networked nonlinear systems is proposed. The desired trajectory tracking objective is achieved via a novel adaptive control strategy, in which the existing concept of pinning control is extended to an adaptive pinning control. The adaptive control is based on a recurrent high‐order neural network identification strategy for...

Yingwen Zhang, Jinhuan Wang, Guanrong Chen

International Journal of Robust and Nonlinear Control > 32 > 13 > 7391 - 7407

This article develops an event‐based control strategy to achieve finite‐time consensus for a chain of nonholonomic multi‐agent systems subject to unknown disturbances. First, the controller switching time is determined for the state coupling of the systems in the chain. Then, adaptive event‐based integral sliding‐mode control protocols with novel triggering functions are proposed, which can avoid...

Formation control for unmanned surface vessels: A game‐theoretic approach

Xiao Fang, Guanghui Wen, Xinghuo Yu, Guanrong Chen

Asian Journal of Control > 24 > 2 > 498 - 509

Two types of formation control problems for a group of unmanned surface vessels (USVs) are investigated by using a game‐theoretic approach. In the two formation frameworks, the USVs have the group formation objective of minimizing the formation errors with their local neighbors. Different from the existing formation control schemes for USVs with only the group objective, the formation control framework...

Controllability analysis for a class of piecewise nonlinear impulsive non‐autonomous systems

Jiayuan Yan, Ding‐Xue Zhang, Bin Hu, Zhi‐Hong Guan, więcej

International Journal of Robust and Nonlinear Control > 32 > 2 > 567 - 582

This article investigates the controllability for a class of piecewise nonlinear impulsive non‐autonomous systems. The problem is addressed by considering the nonlinearities and impulses as perturbations. First, a standard framework is introduced to transform the issue of controllability to the existence of a fixed point by designing a proper admissible control and constructing a nonlinear operator...

Bifurcation analysis of a class of generalized Hénon maps with hidden dynamics

Seiya Amoh, Xu Zhang, Guanrong Chen, Tetsushi Ueta

IEEJ Transactions on Electrical and Electronic Engineering > 16 > 11 > 1456 - 1462

Although continuous systems such as the Chua circuit are known as systems with hidden attractors, hidden attractors also exist in classical discrete maps, such as a generalized Hénon map. A hidden attractor is an attractor that does not overlap with its own attracting region in its vicinity, which makes it difficult to visualize. In this paper, a local bifurcation analysis method for discrete maps...

Scalable consensus filtering for uncertain systems over sensor networks with Round‐Robin protocol

Fei Han, Zidong Wang, Guanrong Chen, Hongli Dong

International Journal of Robust and Nonlinear Control > 31 > 3 > 1051 - 1066

This article is concerned with the scalable distributed H_∞‐consensus filtering problem for a class of discrete time‐varying systems over sensor networks with the Round‐Robin protocol (RRP). The challenge comes from the fact that the time‐varying parameters of the network are subject to randomly occurring norm‐bounded uncertainties and the measurement outputs of the sensor nodes are saturated due to...

Rich dynamics and anticontrol of extinction in a prey–predator system

Marius-F. Danca, Michal Fečkan, Nikolay Kuznetsov, Guanrong Chen

Nonlinear Dynamics > 2019 > 98 > 2 > 1421-1445

This paper reveals some new and rich dynamics of a two-dimensional prey–predator system and to anticontrol the extinction of one of the species. For a particular value of the bifurcation parameter, one of the system variable dynamics is going to extinct, while another remains chaotic. To prevent the extinction, a simple anticontrol algorithm is applied so that the system or bits can escape from the...

Conditional symmetry: bond for attractor growing

Chunbiao Li, Yujie Xu, Guanrong Chen, Yongjian Liu, więcej

Nonlinear Dynamics > 2019 > 95 > 2 > 1245-1256

Coexisting attractors with conditional symmetry exist in separated asymmetric basins of attraction with identical Lyapunov exponents. It is found that when a periodic function is introduced into the offset-boostable variable, infinitely many coexisting attractors may be coined. More interestingly, such coexisting attractors may be hinged together and then grow in the phase space as the time evolves...

Improved known-plaintext attack to permutation-only multimedia ciphers

Leo Yu Zhang, Yuansheng Liu, Cong Wang, Jiantao Zhou, więcej

Information Sciences > 2018 > 430-431 > C > 228-239

Permutation is a commonly used operation in many secure multimedia systems. However, it is fragile against cryptanalysis when used alone. For instance, it is well-known that permutation-only multimedia encryption is insecure against known-plaintext attack (KPA). There exist algorithms that are able to (partially) retrieve the secret permutation sequences in polynomial time with logarithmic amount...

Local communities obstruct global consensus: Naming game on multi-local-world networks

Yang Lou, Guanrong Chen, Zhengping Fan, Luna Xiang

Physica A: Statistical Mechanics and its Applications > 2018 > 492 > C > 1741-1752

Community structure is essential for social communications, where individuals belonging to the same community are much more actively interacting and communicating with each other than those in different communities within the human society. Naming game, on the other hand, is a social communication model that simulates the process of learning a name of an object within a community of humans, where...

Fractional-order PWC systems without zero Lyapunov exponents

Marius-F. Danca, Michal Fečkan, Nikolay V. Kuznetsov, Guanrong Chen

Nonlinear Dynamics > 2018 > 92 > 3 > 1061-1078

In this paper, it is shown numerically that a class of fractional-order piece-wise continuous systems, which depend on a single real bifurcation parameter, have no zero Lyapunov exponents but can be chaotic or hyperchaotic with hidden attractors. Although not analytically proved, this conjecture is verified on several systems including a fractional-order piece-wise continuous hyperchaotic system,...

Liangyin Zhang, Michael Z.Q. Chen, Housheng Su, Guanrong Chen

International Journal of Robust and Nonlinear Control > 28 > 5 > 1871 - 1885

This paper investigates the problem of event‐based synchronization of linear dynamical networks subject to input saturation. The asynchronous neighboring information transmission is triggered by distributed events. The sampled control technique is utilized to exclude both the internal Zeno behavior of each agent and the network Zeno behavior attributed to neighboring agents. Allowing the input saturation...

Further on the controllability of networked multiple‐input–multiple‐output systems, an efficient, necessary, and sufficient condition is derived, where the network topology is directed and weighted and the nodes are higher‐dimensional linear time‐invariant systems. The new condition is easier to verify, which explicitly shows the effects of the network topology, node‐system dynamics, external control...

Communicating with sentences: A multi-word naming game model

Yang Lou, Guanrong Chen, Jianwei Hu

Physica A: Statistical Mechanics and its Applications > 2018 > 490 > C > 857-868

Naming game simulates the process of naming an object by a single word, in which a population of communicating agents can reach global consensus asymptotically through iteratively pair-wise conversations. We propose an extension of the single-word model to a multi-word naming game (MWNG), simulating the case of describing a complex object by a sentence (multiple words). Words are defined in categories,...
