摘要：In this article, we address the problem of attitude estimation for rigid bodies using (possibly time-varying) vector measurements, for which we provide a necessary and sufficient condition of distinguishability. Such a condition is shown to be strictly weaker than those previously used for attitude observer design. Thereafter, we show that even for the single vector case, the resulting condition is sufficient to design almost globally convergent attitude observers, and two explicit designs are...

摘要：The use of game theory for the analysis and design of socio-technological systems has received significant attention as it enables the quantification of the system-level performance while accounting for the presence of individual decision makers. In this context, a popular metric for analyzing the system-level performance is the price of anarchy (PoA), which measures the loss in efficiency caused by distributed decision making. Over the past two decades, significant effort has been devoted to ...

摘要：A new class of nonlinear systems, block logical dynamical systems (BLDSs), is introduced in this note. The existence and uniqueness of solution to BLDSs are first investigated. Then, the topological structure and global stability of BLDSs are analyzed, and a novel criterion is presented to verify the global stability of BLDSs. Finally, the stability of BLDSs is used to study the stability of logical networks subject to time delay. It is shown that the introduction of BLDSs can considerably red...

摘要：In this article, a novel controller design is proposed to solve the finite-time regulation problem of the Heisenberg system, a prototypical nonholonomic system diffeomorphic to the Brockett integrator and many physical systems. Some inherent properties of the Heisenberg system, e.g., the skew-symmetric/diagonal structure, are exploited to obtain a simple-to-tune and bounded control that ensures the finite-time convergence to any point of the state space outside of a zero-measure set. In additi...

摘要：In this work, we consider the problem of event-triggered implementation of control laws designed for the local stabilization of nonlinear systems with center manifolds. We propose event-triggering conditions which are derived from a local input-to-state stability characterization of such systems. The triggering conditions ensure local ultimate boundedness of the trajectories and the existence of a uniform positive lower bound for the inter-event times. The ultimate bound can be made arbitraril...

摘要：In this article, boundary output feedback exponential stabilization and disturbance rejection for a chaotic wave system with superlinear boundary condition and unknown boundary disturbance are investigated. By using measured outputs, an infinite-dimensional disturbance estimator is designed to estimate the unknown boundary disturbance without requiring the conventional boundedness of its derivative and high gain of the estimator. A novel disturbance estimator-based boundary control, comprised ...

摘要：This article investigates the problem of when stochastic nonlinear systems that are $l$th moment asymptotically stabilizable ($l$th MAS) are tolerant to input delay. Substantially different from the existing related literature, our focal point is on a class of stochastic systems that may be neither locally Lipschitz continuous nor linear growth, and not $l$th MAS by smooth feedback. To address the problem of input delay tolerance (IDT), we first present the existence of the solutions for a cla...

摘要：This article investigates the optimal distributed time-varying resource allocation problem for networked high-order systems with time-varying quadratic cost functions. Due to the coexistence of challenges caused by nonidentical Hessian matrices and more complicated agents' dynamics, the extension from existing related results on single-integrator agents is nontrivial. First, a centralized algorithm is proposed to address the optimal time-varying resource allocation problem for high-order-integ...

摘要：In this article, we study the synthesisof a policy in a Markov decision process (MDP) following which an agent reaches a target state in the MDP while minimizing its total discounted cost. The problem combines a reachability criterion with a discounted cost criterion and naturally expresses the completion of a task with probabilistic guarantees and optimal transient performance. We first establish that an optimal policy for the considered formulation may not exist but that there always exists ...

摘要：This article deals with the problem of providing a data-driven solution to the local stabilization of linear systems subject to input saturation. After presenting a model-based solution to this well-studied problem, a systematic method to transform model-driven into data-driven linear matrix inequality (LMI) conditions is presented. This technical solution is demonstrated to be equivalent to the recent advanced results on LMI formulations based on S-procedure or Peterson lemmas. However, the a...
