摘要：This article investigates the problem of distributed secure consensus tracking for leader-following multiagent systems under the presence of sparse data anomalies in the networks. An extra auxiliary function is designed and employed to formulate the interaction gains to mitigate the impact of such unknown sparse anomalies. Different from conventional anomaly detection and isolation methods, the introduction of the auxiliary function can alleviate the wasteful expansion of global sparse anomaly...

摘要：In this article, the fixed-time attitude tracking control for spacecraft is investigated. By introducing dynamic powers, a novel terminal sliding function and a novel nonsingular practical fixed-time tracking control law are developed. In particular, the dynamic powers in the proposed sliding function is constructed via the modified Rodrigues parameters (MRPs) and control law is designed by using the sliding mode variable. An important feature of the proposed dynamic powers-based sliding funct...

摘要：In binary decision making under the linear threshold model, each individual has a time-invariant threshold and is either a conformist, who tends to adopt an action if the population proportion of adopters exceeds their threshold, or a nonconformist, who tends to adopt if it falls short. The resulting decision-making dynamics can be predicted and controlled, provided that the thresholds are known. In practice, however, the thresholds are unknown and often only the evolution of the total number ...

摘要：This article investigates the design problem of periodic event-triggered quantized control (PETQC) for general nonlinear networked control systems (NCSs) with multiple communication channels between the plant and the controller. The transmission of information over these channels is asynchronous, and the transmission instants are determined by a local dynamic event-triggering mechanism (ETM). In each channel, continuous signals are sampled and quantized with a dynamic quantizer (DQ) before bei...

摘要：In this article, we study the robustness of the Nash equilibrium (NE) in aggregative games with coupling constraints. When the constraint parameters are uncertain, the associated NE might be perturbed. It is essential to find a robust NE satisfying all possible constraints affected by the uncertain parameters. Although some methods have been developed for robust NE, these results rely on complete information about the game. We instead consider a scenario when only the uncertain parameters and ...

摘要：We present the first general stability results for nonlinear offset-free model predictive control (MPC). Despite over 20 years of active research, the offset-free MPC literature has not shaken the assumption of closed-loop stability for establishing offset-free performance. In this article, we present a nonlinear offset-free MPC design that is robustly stable with respect to the tracking errors, and thus achieves offset-free performance, despite the plant-model mismatch and persistent disturba...

摘要：In this note, we address the stability problem for a class of hybrid systems, which contains continuous and logical dynamics. First, we introduce the so-called hybrid system in detail, and give the algebraic form of the system utilizing the semi-tensor product (STP, i.e., Cheng product) of matrices. Next, a new stability concept for the hybrid system is proposed by extending the definitions of set stability and exponential stability. After that, several stability criteria are presented by empl...

摘要：Numerical optimization (solving optimization problems using digital computers) currently dominates but has three drawbacks: high energy consumption, poor scalability, and lack of an execution time certificate. To address these challenges, this article explores the recent resurgence of analog computers, proposing a novel paradigm of arbitrarily small execution-time-certified analog optimization (solving optimization problems via analog computers). To achieve ultra-low energy consumption, this p...

摘要：This article presents a generic design approach to the adaptive event-triggered control for a class of nonlinear systems subject to nonlinearly appearing unknown parameters and uncertain nonlinearities. The overall event-triggered control strategy relies on the co-design consisting of parameterized control laws, a parameter switching logic, and an event-triggered sampling mechanism, which guarantees that all the closed-loop states are bounded and the plant state asymptotically converges to the...

摘要：This article studies the adaptive control problem for a class of uncertain strict-feedback nonlinear systems, where both tracking error and full states need to be directly constrained. First, a novel universal constraint approach is introduced, which combines a universal composite barrier function that depends on the tracking error and the output, with universal barrier functions that depend on the remaining states. Compared with existing research, it displays the following appealing features....
