摘要：This work extends the distributed Nash equilibrium seeking algorithm to address multiagent games under time-varying, signed, and undirected communication networks. Initially, based on uniform complete observability for linear time-varying systems, a new analytical framework is developed to determine the necessary and sufficient condition for achieving globally uniformly exponential stability of the error dynamics of the distributed estimator. It is shown that exponential stability is realized ...

摘要：In this article, the zonotopic set-membership estimation (SME) problem is addressed for a class of nonlinear systems subjected to an encoding-decoding scheme, where the measurement information of each sensor is encoded and then transmitted to the remote fusion center. The objective of this article is to develop a zonotopebased weighted measurement fusion (WMF) method to fuse the received decoding signals, and to design a zonotopic SME algorithm that fully utilizes the higher-order partial deri...

摘要：This article focuses on the distributed strategy synthesis to tackle the collaborative optimization problem subject to general set constraints in fixed time. Distinct from the traditional collaborative optimization problem that requires local value functions and their sum being convex, no convexity requirement is essential herein. Besides, the underlying communication network is switching. By bringing in appropriate auxiliary mechanism, a fixed-time distributed optimization strategy is synthes...

摘要：We present a control design and stability analysis for a reaction-diffusion partial differential equation (PDE) with boundary control. The system admits an arbitrary number of unstable eigenvalues and is subject to a time-varying input delay, with an unbounded input operator. The unbounded nature of the input operator requires the stability analysis to be carried out in the H(1 )norm rather than the conventional L(2 )norm of the actuator state. The analysis reveals a cascaded structure compose...

摘要：We study singularly perturbed systems that exhibit input-to-state stability (ISS) with fixed-time properties in the presence of bounded disturbances. In these systems, solutions converge to the origin within a time frame independent of initial conditions when undisturbed, and to a vicinity of the origin when subjected to bounded disturbances. First, we extend the traditional composite Lyapunov method, commonly applied in singular perturbation theory to analyze asymptotic stability, to include ...

摘要：This article presents a two-degree-of-freedom sliding mode control with event-triggered feedback to guarantee robust output tracking for an uncertain plant against matched disturbances. The proposed controller comprises an event-based feedback loop for the plant measurements and the analog feedthrough path for the tracking (reference) signal, which is generated by an exogenous system. Here, the event-triggering mechanism uses only the feedback signals, unlike the existing works, and thus, it r...

摘要：In this article, we explore two data-driven methods to perform fault estimation on a linear time-invariant discrete-time state-space model, whose state equation is affected by both disturbances and actuator faults. We first investigate the design of a residual generator, which is based on a dead-beat unknown-input observer. Necessary and sufficient conditions for the problem solvability, assuming that the system matrices are known, are first presented. Then, we prove that, under suitable assum...

摘要：When interacting with other decision-making agents in nonadversarial scenarios, it is critical for an autonomous agent to have inferable behavior. The agent's actions must convey its intention and strategy. We model the inferability problem using Stackelberg games with observations where a leader and a follower repeatedly interact. During the interactions, the leader uses a fixed mixed strategy. The follower does not know the leader's strategy and dynamically reacts to the statistically inferr...

摘要：In this article, we extend the recently developed adaptive generalized parameter estimation-based observer design technique for state-affine systems to the practically important case when, besides unknown parameters, the output signal is perturbed by an additive disturbance generated by an exosystem whose parameters are unknown. Our main contribution is that we treat-for the first time-the case when the disturbance appears in the measured output. It is important to say that this scenario is mu...

摘要：This note focuses on the dissipativity and stability of highly nonlinear hybrid stochastic differential delay equations (HSDDEs). First, based on the results of previous research, a series of new time-varying Halanay-type inequalities is established, which overcomes the dependence of drift and diffusion terms on linear growth conditions in stochastic systems and expands the application of Halanay inequalities in highly nonlinear stochastic systems. Then, the dissipativity and stability conditi...
