摘要：The existence of a control barrier function (CBF) for a control-affine system provides a powerful design tool to ensure safety. Any controller that satisfies the CBF condition and ensures that the trajectories of the closed-loop system are well defined makes the zero superlevel set forward invariant. Such a controller is referred to as safe. This article studies the regularity properties of the minimum-norm safe controller as a stepping stone toward the design of general continuous safe feedba...

摘要：This article focuses on the analysis for stability of semi-Markov jump stochastic systems in pth moment sense. First of all, the extended system method is constructed, which can transform the analysis of semi-Markov jump stochastic systems in pth moment sense into the analysis of the extended systems. With the help of the extended system method, the necessary and sufficient conditions for stability in the even-order moment sense are derived. Finally, several examples are given to illustrate th...

摘要：We address the problem of resilient consensus in second-order multiagent networks (MANs) with a time-varying set of malicious agents. Existing research typically assumes a static set of malicious agents. However, in real-world scenarios, network attacks and recoveries may lead to dynamic changes in the roles of agents. To overcome this challenge, a novel adaptive weighted subsequence reduction (AWSR) is proposed for resilient consensus in MANs with a dynamic malicious agent set. Based on the A...

摘要：This article addresses the problem of tracking control for an unknown nonlinear system with time-varying bounded disturbance subjected to prescribed performance and input constraints (PIC). Since the simultaneous prescription of PIC involves a tradeoff, we propose an analytical feasibility condition to prescribe a feasible PIC, which also results in a feasible initial state set as a corollary. In addition, we propose an approximation-free controller to ensure the tracking performance meets the...

摘要：This article addresses the problem of event-based fully distributed state estimation for an unperturbed linear time-invariant system in the presence of communication link faults. In a networked system, each agent is capable of constructing its local observer adaptively and transmitting its estimation to neighbors through discrete communication, thereby achieving accurate estimation of the system state while saving communication resources effectively. Specifically, first, the target system stat...

摘要：This article proposes and analyzes a distributed filter where the consensus term is a virtual output rather than the local state estimate. This feature allows for reducing the data transmitted among nodes at each intermediate step, namely, instead of exchanging a vector of the dimension of the state, nodes exchange a vector of the dimension of the rank of the total output matrix. The main finding is that the convergence to the performance of the centralized Kalman filter and mean-square bounde...

摘要：Error dynamics captures the evolution of state errors between two distinct trajectories that are governed by the same dynamical system rule but initiated and/or perturbed differently. It is essential to analyze the error behavior of a state observer on a matrix Lie group for precise estimation. This article concentrates on the examination of error dynamics in affine group systems when exposed to external disturbances or random noises. To this end, we first characterize linear group systems equ...

摘要：Strategic decisions are often made over multiple periods of time, wherein decisions made earlier impact a competitor's success in later stages. In this article, we study these dynamics in General Lotto games, a class of models describing the competitive allocation of resources between two opposing players. We propose a two-stage formulation where one of the players has reserved resources that can be strategically preallocated across the battlefields in the first stage of the game as reinforcem...

摘要：The optimal transmission scheduling over packet length-dependent lossy networks is investigated. A set of sensors observe some linear time-invariant systems, and obtain their local state estimates using Kalman filters independently. The local state estimates are encoded in a data packet, which is sent to a remote estimator over packet length-dependent lossy networks, i.e., the packet arrival probability is exponentially decreasing with the packet length. The tradeoff arises between the packet ...

摘要：In this article, we examine the model reference adaptive control problem when the commonly used projection algorithm is utilized, subject to several common assumptions on the set of admissible parameters, in particular a compactness constraint as well as knowledge of the sign of the high-frequency gain. It is proven in the literature that for this setup, the closed-loop system is bounded-input bounded-state; since the closed-loop system is not linear time-invariant, this does not imply a bound...
