摘要：This note proposes to leverage the emerging learning techniques to devise a multiagent online source seeking algorithm under unknown environments. Of particular significance in our problem setups are: first, the underlying environment is not only unknown, but dynamically changing and also perturbed by two types of nonstochastic disturbances, and second, a group of agents is deployed and expected to cooperatively seek as many sources as possible. Correspondingly, a new technique of the discount...

摘要：In this article, we study a class of two-player deterministic finite-horizon difference games with coupled inequality constraints, where each player has two types of decision variables: one involving sequential interactions and the other simultaneous interactions. We refer to this class of games as quasi-hierarchical dynamic games and define a solution concept called the feedback Stackelberg-Nash (FSN) equilibrium. Under separability assumption on cost functions, we provide a recursive formula...

摘要：This article provides a cascade observer design framework for a class of disturbed uniformly observable systems with arbitrary long (constant and known) time delays in both output and state variables. Two fundamental design features are worth mentioning to better appreciate the involved contribution of this article. First, a basic cascade observer is designed assuming that the structure of the system's nonlinear dynamics is triangular with respect to the actual and delayed states and that the ...

摘要：We propose a new framework for solving online linear quadratic (LQ) control problems with time-varying cost matrices that are known only up to the current time or over a short preview window. Our framework involves using revealed cost matrices to predict the unknown optimal trajectory, and then using a tracking controller to drive the system toward this prediction. We adopted the notion of dynamic regret to measure and bound the resulting quality of control decisions with and without system di...

摘要：This article is concerned with the problem of mean-square stability and stabilization under an energy harvesting sensor, where the sensor can harvest energy from the external environment. When the sensor's energy is insufficient to maintain regular communication between the sensor and the controller, the sampled data packets are regarded as missing. Otherwise, they can be successfully transmitted in the communication network. To address this problem, we first establish a continuous-time modeli...

摘要：Cooperation and competition relationships are ubiquitous in multiagent networks. A good cooperative relationship is likely to prompt neighboring agents to draw close each other, while a competitive relationship can easily lead to neighboring agents moving away from each other. This article aims to investigate how to implement formation containment for multiagent networks with both cooperative and competitive interactions in 2-D space, where the followers are unaware of the topology information...

摘要：This article investigates defense strategies against denial-of-service (DoS) attacks in remote state estimation. When DoS attacks disrupt sensor communication, the signal-to-interference-and-noise ratio decreases, thereby reducing the probability of successful state estimate transmission to the remote estimator and ultimately degrading estimation accuracy. The interaction between the sensor and attacker is modeled as a nonzero-sum Stackelberg game, where the smart sensor first determines a com...

摘要：Direct data-driven control has emerged as a powerful alternative to traditional state-space model-based methods by directly learning control policies from data. Nevertheless, ensuring that control actions adhere to specific physical and safety constraints, a challenge often overlooked in existing direct data-driven approaches focused primarily on stability and robustness, is crucial for real-world deployment. This article addresses this gap by designing a robust data-driven state feedback cont...

摘要：In this article, we present a distributed source-seeking and flocking-control method for networked multiagent systems with nonholonomic constraints. Based solely on identical on-board sensor systems, which measure the source local field, the group objective is attained by appointing a leader agent to seek the source while the remaining follower agents safely form a cohesive flocking with their neighbors using a distributed flocking control law in a connectivity-preserved undirected network. To...

摘要：This article focuses on the communication-efficient distributed Nash equilibrium seeking (DNES) of multiagent systems (MASs) under unreliable communications. The unreliability is characterized as irregular topology switchings (e.g., due to communication failures, adversarial attacks, or other agents' blockages), which will often cause disconnected communication topologies and further result in failure of DNES. To overcome this challenge while reducing data transmissions, a novel dynamic event-...
