In this paper, an adaptive fuzzy hierarchical sliding-mode control method for a class of multiinput multioutput unknown nonlinear time-delay systems with input saturation is proposed. The studied system first transformed into equivalent system. Subsequently, based on technology and the concept design, set controllers are designed new defined by using to approximate uncertain functions compensate saturation. Choosing appropriate Lyapunov-Krasovskii function, it theoretically proved that all...

Structural balance theory has been developed in sociology and psychology to explain how interacting agents, e.g., countries, political parties, opinionated individuals, with mixed trust mistrust relationships evolve into polarized camps. Recent results have shown that structural is necessary for polarization networks fixed, strongly connected neighbor when the opinion dynamics are described by DeGroot-type averaging rules. We develop this line of research paper two steps. First, we consider...

This article investigates the stability of positive switched linear systems. We start from motivating examples and focus on case when each subsystem is marginally stable (in sense that all eigenvalues matrix are in closed left-half plane with those imaginary axis simple) instead asymptotically stable. A weak excitation condition first proposed such considered system exponentially An extension to without dwell time assumption also presented. Then, we study influence time-varying delay system....

This paper is concerned with the sampled-data-based consensus problem of heterogeneous multiagent systems under directed graph topology communication failure. The system consists first-order and second-order integrators. Consensus may not be guaranteed if failure always happens. However, frequency length satisfy certain conditions, considered can reached. In particular, we introduce concepts length. Then, help switching technique Lyapunov stability theory, sufficient conditions are derived...

In this article, we study the formation problem for a group of mobile agents in plane, which are required to maintain distribution pattern, as well rotate around or remain static relative static/moving target. The prescribed pattern is class general formations where distances between neighboring each agent and target do not need be equal. Each modeled double integrator can merely perceive information its neighbors, acceleration order solve problem, limit-cycle-based controller design...

The roundabouts exist widely in urban road networks and reduce the number of traffic crashes by reducing vehicle conflicts. However, restrictions at entrances exits increase collision possibility between vehicles as they enter or leave roundabouts. Focusing on driving scenes a roundabout, this article proposes multivehicle coordinated lane change strategy for mandatory vehicles. First, depending fluctuation acceleration, driver's aggressive coefficient is defined. Second, according to...

Adaptive robust control technique is investigated to devise trajectory tracking event-triggered controller for a class of uncertain nonlinear systems. Different from most existing results, this article divides the entire input into two parts, including model compensation term and term, which are separately dealt with by means special triggered mechanisms. The advantage separation that system reduces magnitude chattering amplitude within inputs. To balance information updating frequency...

To address the challenges in battery health management, this paper introduces a physics-informed neural network predictor-estimator scheme. In framework, predictor forecasts degradation, setting benchmarks for estimator, while estimator provides calibrations as substitution to infeasible measurement techniques. For design, linear-exponential model is employed two-stage degradation prediction, enabling online parameter updates and knee point detection. three networks embedded with Coulomb...

This paper is concerned with the consensus problem of general linear dynamic multiagent systems stochastic sampling. In this paper, sampling intervals randomly switch between two different values. The communication topology agents fixed and directed. Full- reduced-order observers are designed based on neighbor agents' relative output information. algorithms to construct such also provided. By using estimated states agents, observer-based protocol presented. Sufficient conditions ensure in...

We provide new insight into the somewhat obscure definition of Sarymsakov class stochastic matrices and use it to construct a necessary sufficient condition for convergence products matrices. Such result is critical in establishing effectiveness distributed coordination algorithms multi-agent systems enables us investigate specific task with asynchronous update events. The set scrambling matrices, subclass class, utilized establish agents' states even when there no common clock agents...

This paper proposes a novel control strategy to improve the stability performance for four-wheel independent drive electric vehicles in critical cornering by introducing supervision mechanism yaw moment and slip ratio regulation simultaneously. The proposed is three-level structure: first level composed of controller longitudinal velocity controller; second made up tyre force distributor; third consists regulator. To begin with, developed supervise vehicle driving states determine whether...

Using Lyapunov stability theory control method, receiver will achieve drive would be estimated by receiver. Then proposed is used for secure communications based on communication schemes including masking, modulation, shift key strategies. Since two systems are almost unknown, it more difficult intruder to extract useful message from...

This paper investigates a problem of stabilization control design. A novel triggering mechanism, called parallel-triggering is proposed to handle the nonlinear/linear systems. Compared with existing conditions, through fully considering relationship between variation Lyapunov function and system states, we propose without requirement that derivative negative at all-time instants. Under new number executions tasks can be significantly reduced similar stability performance kept. Particularly,...

This article considers remote state estimation in cyber-physical systems (CPSs) with multiple sensors. Each plant is modeled by a discrete-time stochastic linear system measurements of each sensor transmitted to the corresponding estimator over shared communication network when their securities are interdependent due network-induced risks. A dynamic nonzero-sum game asymmetric information formulated which subject resource budget constraint needs decide whether invest security for sending...
