摘要：This article explores the automatic verification of bounded synchronization for heterogeneous polynomial networked systems (HPNSs) with polynomial coupling function. In our method, the generalized blended dynamics is presented to analyze the heterogeneity of systems. By utilizing polynomial Lyapunov functions, the synchronization criterion for HPNSs under directed topology is presented, along with a bounded set where the synchronization errors of HPNSs reside when the time progresses towards i...

摘要：In this article, we study the tracking or sidewise controllability of the heat equation. More precisely, we seek controls that, acting on part of the boundary of the domain where the heat process evolves, aim to assure that the normal trace or flux on the complementary set tracks a given trajectory. The dual equivalent observability problem is identified. It consists of estimating the boundary sources, localized on a given subset of the boundary, out of boundary measurements on the complementa...

摘要：In this article, we extend the notion of time-domain moment to a class of general systems of nonlinear differential-algebraic equations. In addition, a new family of systems achieving moment matching is constructed. Provided that mild conditions hold, and for any given dimension at least as large as that of the signal generator, it is proven that this family of systems parameterizes all systems achieving moment matching. Four illustrative examples are provided. In the first and second example,...

摘要：In this article, we consider tube model predictive control of discrete-time linear systems subject to additive bounded disturbances and mixed state and control constraints. An improved tube model predictive controller, leveraging the advantages and mitigating the disadvantages of three pivotal existing methods, is proposed. Its computational aspects and theoretical properties are thoroughly discussed and compared with its predecessors. Two numerical examples are provided to illustrate the bene...

摘要：Distributed Nash equilibrium (NE) seeking problems for networked games have been widely investigated in recent years. Despite the increasing attention, communication expenditure is becoming a major bottleneck for scaling up distributed approaches within limited communication bandwidth between agents. To reduce communication cost, an efficient event-triggered and compressed distributed NE seeking (ETC-DNES) algorithm is proposed in this article to obtain an NE for games over directed graphs, wh...

摘要：In this article, a rate-coded secure control is investigated for the consensus of multiagent systems (MASs). The challenge lies in how to design a broadcasting protocol when the communication bit is critical, and to strengthen its security at the same time. A novel rate-coded algorithm is designed for MASs from an encoding-decoding viewpoint, where only an encrypted L-length codeword, instead of the sensitive system information, is transmitted over the network between each agent and its neighb...

摘要：This article tackles the asynchronous cooperative output regulation problem for heterogeneous nonlinear multiagent systems (MASs) characterized by jointly connected switching topologies. Considering the heterogeneity inherent in the MASs, we propose two distributed asynchronous observers. The first observer is developed to estimate the exosystem matrix, and the second is tailored to estimate the exosystem state. To guarantee the estimation accuracy of these observers, we formulate a relationsh...

摘要：This technical note deals with asymptotic stabilization of general nonlinear discrete-time systems by dynamic output feedback control. First, a sufficient condition for the dynamic output feedback stabilization with the closed-loop domain of attraction (DOA) estimation is given. For a given Lyapunov function of the plant state and the controller state, the negative-definite domain (NDD) in the (z+-u-z-y)-space is proposed, where z+, u, z, and y denote the next controller state, the current con...

摘要：In this work, we propose a collision-free source-seeking control framework for a unicycle robot traversing an unknown cluttered environment. In this framework, obstacle avoidance is guided by the control barrier functions (CBF) embedded in quadratic programming, and the source-seeking control relies solely on the use of onboard sensors that measure the signal strength of the source. To tackle the mixed relative degree and avoid the undesired position offset for the nonholonomic unicycle model,...

摘要：Autonomous synchronization presents a novel paradigm that circumvents the need for prior knowledge of target agent dynamics in the conventional synchronization of heterogeneous multiagent systems (MASs). It employs a dynamics update law and a state synchronizing control law, collectively termed a two-level controller, to facilitate synchronization in heterogeneous MASs autonomously. Nevertheless, the existing theory is constrained by the requirement of network topology information for calculat...
