摘要：During the analysis and design of a network system, a frequently encountered situation is when the network structure is known but the node dynamics is practically unknown. Thus, structural analysis in which the prior knowledge is mostly about the network structure has received attention in recent years. Motivated by this line of research, this article focuses on a structural design problem called the structural equilibrium control problem, which is used to find a sign pattern in the control in...

摘要：This article considers a discrete-time robust optimal control problem on matrix Lie groups. The underlying system is assumed to be perturbed by exogenous unmeasured bounded disturbances, and the control problem is posed as a min-max optimal control wherein the disturbance is the adversary and tries to maximize a cost that the control tries to minimize. Assuming the existence of a saddle point in the problem, we present a version of the Pontryagin maximum principle (PMP) that encapsulates first...

摘要：The existence of an optimal reverse-waterfilling algorithm to compute the nonanticipative rate distortion function (NRDF) for time-invariant vector-valued Gauss-Markov processes with a mean-squared-error distortion has been an open question since the pioneering work of Tatikonda et al. on stochastic linear control over a communication channel, in 2004. In this article, we derive strong structural properties on the time-invariant multidimensional Gauss-Markov processes that allow for an optimiz...

摘要：This article focuses on the control of nonlinear systems with redundant actuation, where the number of actuators is higher than the number of controllable degrees of freedom. To effectively handle actuation redundancy, we propose a control allocation (CA) approach that combines numerical optimization methods with control Lyapunov and control barrier functions. The inclusion of control Lyapunov functions enhances the CA's ability to minimize performance loss in the presence of unattainable virt...

摘要：In this article, we study stochastic multiarmed bandits with many players. The players do not know the number of players, cannot communicate with each other, and if multiple players select a common arm, they collide and none of them receive any reward. We consider the static scenario, where the number of players remains fixed, and the dynamic scenario, where the players enter and leave at any time. We provide algorithms based on a novel trekking approach that guarantees constant regret for the...

摘要：This article considers the privacy-preserving distributed Nash equilibrium seeking strategy design for average aggregative games, in which the players' objective functions are considered to be sensitive information to be protected. In particular, we consider that the game is free of central node and the aggregate information is not directly available to the players. As there is no central authority to provide the aggregate information required by each player to update their actions, a dynamic ...

摘要：This article investigates the cluster consensus control problem for general linear multiagent systems. The focus of this article is especially to solve the following problem: in what kinds of connection scenarios can agents achieve cluster consensus regardless of the coupling strength (CCRCS). Different from existing literature, this article extends the case to general partition graphs, including both acyclic and cyclic partition cases. New analysis methods are put forward. It is proved that, ...

摘要：This article deals with the problem of controlling the average state of a large-scale linear network to a constant reference value. We design an output-feedback controller such that no information about state vector or system matrices is needed. For this controller to have arbitrary positive gains, it is sufficient that only a sign condition on system matrices should be satisfied. To assure that the states of the network are close to the average state, the problem of deviation minimization is ...

摘要：This article considers the optimal control problem for path-constrained switched systems with guaranteed feasibility. First, a method is proposed to reduce continuous path constraints of the switched systems into discrete abstract constraints in terms of the switch time vector and the input. Second, differentiability of the optimal value function, i.e., the cost function optimized over the input, is analyzed by using perturbation analysis theory. For a given switch time vector, the derivative ...

摘要：This article is concerned with robust stability analysis of feedback interconnections of nonlinear systems using integral quadratic constraints (IQCs). Its main purpose involves reconciling hard (a.k.a. unconditional) IQC and soft (a.k.a. conditional) IQC-based analysis. In particular, it is shown that the hard IQC stability result can be recovered from the soft IQC theory. The hard IQC approach is closely related to the dissipativity theory, whereas the soft IQC approach makes use of homotopi...
