摘要:This article deals with the stabilization of positive equilibria of dynamical systems whose state variables describe positive quantities. This article elucidates and tackles two obstacles. One is the limitation to systems with Metzler matrices and their nonlinear generalization called cooperative systems, which fall into the monotonicity with respect to positive orthants. For positive equilibria, those properties are neither necessary nor sufficient for positivity of state variables. Due to no...

摘要:This technical note considers the problem of global adaptive control via state-quantized feedback for a class of nonlinear systems with large parametric uncertainty. First, a dynamic logarithmic quantizer for discontinuous signals is developed, which can be viewed as a concatenation of novel hysteresis logarithmic quantizers with distinct dead zones. Then, based on the sector bound property of the novel quantizer, a hybrid-gain scaling approach is proposed to achieve global adaptive asymptotic...

摘要:Late-lumping feedback design for infinite-dimensional linear systems with unbounded input operators is considered. The proposed scheme is suitable for the approximation of backstepping and flatness-based designs and relies on a decomposition of the feedback into a bounded and an unbounded part. Approximation applies to the bounded part only, while the unbounded part is assumed to allow for an exact realization. Based on spectral results, the convergence of the closed-loop dynamics to the desir...

摘要:This article investigates target-attacker-defender (TAD) differential games comprising an active target, multiple attackers, and defenders, including some anomalous agents within the defenders' team. First, we introduce two types of anomalous defenders, characterized by coefficients in the performance metrics, termed greedy and fearful. Then, we explore two distinct scenarios: first, when the attackers possess unlimited observation capabilities while visibility limitations constrain the defend...

摘要:Game-theoretic model predictive control (or receding horizon games) is an emerging control methodology for multiagent systems that generates control actions by solving a dynamic game with coupling constraints in a receding-horizon fashion. This control paradigm has recently received increasing attention in various application fields, including robotics, autonomous driving, traffic networks, and energy grids, due to its ability to model the competitive nature of self-interested agents with shar...

摘要:In the research on stabilizing continuous-time randomly sampled systems (RSSs) via a discrete-time approach, the objects of analysis and synthesis are mostly discrete-time stochastic models that have undergone discretization rather than resulting continuous-time systems. However, despite their close relation, the stability of discrete-time stochastic models may not be equivalent to that of the resulting continuous-time systems when the actual sampling interval fluctuates around an ideal sampli...

摘要:This article introduces the new concepts of functional controllability and functional stabilizability, and establishes their duality with functional observability and functional detectability, respectively. A generalized separation principle is presented, under which the classical separation principle emerges as a special case. Conditions for the existence of functional controllers of a specified order are derived. Notably, the proposed design framework does not require full controllability. I...

摘要:In this article, we consider a strategic game played by a group of agents on a set of opinion dynamics models. The models are all Friedkin-Johnsen (FJ) models, which are independent of each other (we call them parallel FJ models). The task of an agent is to maximize her overall social power by allocating a given budget of stubbornness across the parallel FJ models. For this game, the cost function is shown to be convex in the action profile set, but discontinuous at some boundary points when f...

摘要:This article investigates the state consensus problem of uncertain multi-input multioutput (MIMO) multiagent systems (MASs) over a directed graph, where only the outputs of the agents are available. We consider two types of agent dynamics, namely, square systems with equal input-output dimensions, and nonsquare systems where outputs exceed inputs. For square systems, an adaptive consensus algorithm is developed that interacts solely through relative output information. Luenbergerlike observers...

摘要:Directional motion toward a specified destination is a common occurrence in physical processes and human societal activities. Utilizing this prior information can significantly improve the prediction and filtering performance of system models. This article focuses on the reconstruction and state filtering of a linear dynamic system model with destination constraints in the set-valued framework. We treat destination constraints as inherent information in the state evolution process and employ c...
