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：Toward bridging classical optimal control and online learning, regret minimization has recently been proposed as a control design criterion. This competitive paradigm penalizes the loss relative to the optimal control actions chosen by a clairvoyant policy, and allows tracking the optimal performance in hindsight no matter how disturbances are generated. In this article, we propose the first receding horizon scheme based on the repeated computation of finite horizon regret-optimal policies, an...

摘要：This article establishes a systematic methodology to improve the utilization efficiency of probabilistic information for the stability analysis and stabilizing control of discrete-time semi-Markov jump linear systems (SMJLSs). The transition and sojourn information is incompletely known, and the coupling between the known (or unknown) transition and unknown (or known) sojourn information renders the known probabilistic information difficult to be fully leveraged, which can lead to conservative...

摘要：This article proposes a modified Cucker-Smale model in view of a double-integrator multiagent dynamic system on complete Riemannian manifolds with an attractive-repulsive force. Then, its flocking behaviors, such as collision avoidance, velocity alignment, and aggregation, are researched. On the basis of covariant derivative and parallel transport, the original Cucker-Smale model on complete Riemannian manifolds can reach velocity alignment. By using the logarithm map on Riemannian manifolds, ...

摘要：In this article, the distributed interval observer design problem for a continuous-time linear time-invariant system with unknown external disturbance and measurement noise is revisited. By performing detectability decomposition for partial outputs of each sensor from the system matrix, a classical interval observer and an internally positive representation-based interval observer are designed for the detectable and the undetectable subsystems, respectively, which reduces the order of the resu...

摘要：We consider Lurye systems, whose nonlinear operator is characterized by a nonlinearity that is bounded above and below by monotone functions. Absolute stability can be established using a subclass of the O'Shea-Zames-Falb multipliers. We develop phase conditions for both continuous-time and discrete-time systems under which there can be no such suitable multiplier for the transfer function of a given plant. In discrete time the condition can be tested via a linear program, while in continuous ...

摘要：Robustness functions provide quantitative scores to measure the satisfaction of temporal logic formulas. We introduce a general class of parameterized robustness functions for signal temporal logic (STL), and demonstrate how it can be used for control problems involving STL specifications. We employ power means and generalized functional means to capture robust satisfaction over space and time. We show that our general definition encompasses many of the STL robustness functions in the literatu...

摘要：In this article, we address a class of Nash games with nonconvex coupling constraints for which we define a novel notion of local equilibrium, here named local generalized Nash equilibrium (LGNE). Our first technical contribution is to show the stability in the game theoretic sense of these equilibria on a specific local subset of the original feasible set. Remarkably, we show that the proposed notion of local equilibrium can be equivalently formulated as the solution of a quasi-variational in...
