摘要：In this note, we propose a framework for the event-based semiglobal practical stabilization of nonlinear continuous-time systems based on limited amount of information. Following an emulation approach, it is required the availability of a convergent state observer and of a global asymptotic stabilizer in continuous time, generally depending on the estimated state and on the measured output. We then introduce time sampling, quantizations on the input, observed state and output signals, and a pe...

摘要：This article is concerned with the stabilization problem for a class of feedforward nonlinear systems via pulsewidth-modulated (PWM) controllers. First, a state observer, which features a dynamic predictor and a jumping update, is designed such that the unavailable full system state can be accurately estimated. With the obtained state estimations, a reference signal is also constructed. Second, a three-level-state-dependent PWM controller is proposed, which switches among three prescribed stat...

摘要：This work is devoted to stochastic functional differential equations with past-dependent random switching, in which the switching process is allowed to take values in a countable state space. Such processes are rather versatile and arise in a wide variety of applications. A central issue considered in this article is stability. The conditions provided are more general than the existing work. After getting the desired stability results, several applications, including linear systems, linearizat...

摘要：In this technical note, we study a finite double-sided queue with multiple customer types, where two-sided arrivals follow independent Poisson processes. Customers arrive to one side and match with queued customers on the opposite side. A gatekeeper who has complete knowledge of the number of customers decides to accept or reject each arrival. The difference between customer types is defined by the customer's profit to the gatekeeper. Assuming no matching time between the two-sided customers, ...

摘要：In this article, we develop a novel contraction framework for the stability analysis of discrete-time nonlinear systems with parameters following stochastic processes. For general stochastic processes, we first provide a sufficient condition for uniform incremental exponential stability (UIES) in the first moment with respect to a Riemannian metric. Then, focusing on the Euclidean distance, we present a necessary and sufficient condition for UIES in the second moment. By virtue of studying gen...

摘要：Underapproximations of reachable sets and tubes have been receiving growing research attention due to their important roles in control synthesis and verification. Available underapproximation methods applicable to continuous-time linear systems typically assume the ability to compute transition matrices and their integrals exactly, which is not feasible in general, and/or suffer from high computational costs. In this note, we attempt to overcome these drawbacks for a class of linear time-invar...

摘要：In this article, we consider the problem of controlling the group behavior of a large number of dynamic systems that are constantly interacting with each other. These systems are assumed to have identical dynamics (e.g., flocks of birds, UAV swarms) and their group behavior can be modeled by a distribution. Thus, this problem can be viewed as an optimal control problem over the space of distributions. We propose a novel algorithm to compute a feedback control strategy so that, when adopted by ...

摘要：Existing research results on regressor-based control use the linear parameterization of the dynamic equation into a known regressor matrix and an uncertain parameter vector. In this note, we show that the well-known robust controller that assumes a known regressor matrix can yield undesirable performance and poor robustness capabilities if there is uncertainty in the regressor matrix, especially when dealing with larger robots. The novelty of our result lies in accounting for uncertainties in ...

摘要：This article is concerned with distributed Nash equilibrium (NE) problem for multiplayer games under the Round-Robin (RR) protocol. For the purpose of effectively mitigating data congestion and saving communication resources, the RR protocol is adopted for each player, under which the player is permitted to transmit data to only one of its neighbors at each time instant. The resulting protocol-induced communication graph become time-varying and even disconnected, even though the original graph...

摘要：The objective of this article is to study containment control problems for multiagent systems with position constraints and switching topologies. The first contribution is to find conditions under which all agents have the possibility to realize containment control in a distributed manner while the position of each agent is constrained to lie in a specific constraint set in the presence of possible conflicts of the position constraints and the requirement of the convergence into the convex hul...
