摘要：New stability conditions for cluster synchronization of Kuramoto oscillators are presented. Our approach is based on averaging criteria, but the standard method for stability analysis cannot be directly applied due to the lack of uniform continuity with respect to a perturbation parameter. First, we overcome this technical difficulty with the help of nonmonotonic Lyapunov functions. Our extensions of averaging criteria are the key to unify the existing cluster synchronization conditions: 1) th...

摘要：Optimal control problems can be solved via a one-shot (single) optimization or a sequence of optimization using dynamic programming (DP). However, the computation of their global optima often faces NP-hardness, and thus only locally optimal solutions may be obtained at best. In this work, we consider the discrete-time finite-horizon optimal control problem in both deterministic and stochastic cases and study the optimization landscapes associated with two different approaches: one-shot and DP....

摘要：This note deals with the analysis of input/output-to-state stability (IOSS) and construction of state-norm estimators for continuous-time switched nonlinear systems under restricted switching. Our contributions are twofold. First, given a family of systems, possibly containing unstable dynamics, a set of admissible switches between the subsystems and admissible minimum and maximum dwell times on the subsystems, we identify a class of switching signals that obeys the given restrictions and pres...

摘要：We introduce ( gamma, delta )-similarity, a notion of system comparison that measures to what extent two stable linear dynamical systems behave similarly in an input-output sense. This behavioral similarity is characterized by measuring the sensitivity of the difference between the two output trajectories in terms of the external inputs to the two potentially nondeterministic systems. As such, ( gamma, delta )-similarity is a notion that characterizes approximation of input-output behavior, wh...

摘要：This article builds the theoretical foundations for dynamic mode decomposition (DMD) of control-affine dynamical systems by leveraging the theory of vector-valued reproducing kernel Hilbert spaces (RKHSs). Specifically, control Liouville operators and control occupation kernels are introduced to separate the drift dynamics from the input dynamics. A given feedback controller is represented through a multiplication operator, and a composition of the control Liouville operator and the multiplica...

摘要：This article revisits the event-triggered control problem from a data-driven perspective, where unknown continuous-time linear systems subject to disturbances are taken into account. Using data information collected offline instead of accurate system model information, a data-driven dynamic event-triggered control scheme is developed in this article. An update algorithm is proposed for dynamically updating the event-triggered function embedded in the event-triggered mechanism (ETM). Thanks to ...

摘要：In this article, we propose a framework for synthesizing reach-avoid controllers for deterministic systems modeled by ordinary differential equations and stochastic systems modeled by stochastic differential equations based on the notion of control guidance-barrier functions. We first consider deterministic systems and aim to synthesize a reach-avoid controller that modifies a nominal controller in a minimal way to enforce the reach-avoid objective. This objective ensures that the system enter...

摘要：The design of optimization algorithms has long been a matter of art, and it calls for the systematic development of methods in which algorithms can be analyzed, designed, and benchmarked with regard to their key attributes such as efficiency, complexity, and robustness. This article answers this need by providing a frequency-domain framework for algorithm analysis and synthesis, with a particular emphasis on distributed optimization problems. We propose a general class of gradient-based distri...

摘要：In this article, the problem of global stabilization for a class of nonlinear strict-feedback time-delay systems is addressed by adopting the adaptive parameter estimation method and backstepping technique. The Lyapunov-Krasovskii functionals with static gain functions are designed in each step of the backstepping process. With the help of the sufficiently smooth projection operator, the relationship between the Lyapunov-Krasovskii functional and the previous virtual control laws is establishe...

摘要：In this article, we investigate the uniform exponential stability of a semidiscrete scheme for a Schrodinger equation under boundary stabilizing feedback control in the natural state space L-2(0,1). This study is significant since a time domain energy multiplier that allows proving the exponential stability of this continuous Schrodinger system has not yet found, thus leading to a major mathematical challenge to the uniform exponential stability of the corresponding semidiscretization systems,...
