摘要：To achieve a parsimonious model, it is necessary to rank the importance of input variables according to some measures. The problem is nontrivial in the setting of nonlinear and nonparametric system identification. Difficulties lie in the lack of structural information of the unknown system, unknown underlying probabilistic distributions, and unknown nonlinear correlations of variables. In this article, we present a way to rank variables according to goodness of fit (GoF). Asymptotic results ar...

摘要：We characterize a class of systems for which the H-infinity optimal control problem can be simplified in a way that enables sparse solutions and efficient computation. For a subclass of the systems, an optimal controller can be explicitly expressed in terms of the matrices of the system's state-space representation. In many applications, the controller given by this formula, which is static, can be implemented in a decentralized or distributed fashion. Examples are temperature dynamics in buil...

摘要：In order to deal with issues caused by the increasing penetration of renewable resources in power systems, this article proposes a novel distributed frequency control algorithm for each generating unit and controllable load in a transmission network to replace the conventional automatic generation control. The targets of the proposed control algorithm are twofold. First, it is to restore the nominal frequency and scheduled net interarea power exchanges after an active power mismatch between ge...

摘要：In this article, we study the distributed generalized Nash equilibrium (GNE) seeking problem of noncooperative games in dynamic environments. Each player in the game aims to minimize its own time-varying cost function subject to a local action set. The action sets of all players are coupled through a shared convex inequality constraint. Each player can only have access to its own cost function, its own set constraint, and a local block of the inequality constraint, and can only communicate wit...

摘要：In the standard linear, time-invariant feedback system, controllers that achieve diagonal decoupling and closed-loop stability exist if and only if the plant satisfies the diagonal denominator condition or has no coinciding poles and zeros in the region of instability. A simple and systematic decoupling design procedure is presented under each of these conditions. The closed-loop poles can be placed at any desired points, and free parameters are included for satisfying additional design object...

摘要：This article investigates input-to-state stability (ISS) of impulsive delay systems with multiple impulses. We provide sufficient conditions in terms of exponential ISS-Lyapunov functions coupled with Razumikhin-type conditions for establishing the ISS property, where the possibility of the effects of multiple impulses on ISS is fully considered. It shows that when the continuous dynamics are ISS and the discrete dynamics that govern the jumps involve multiple impulses, the ISS property can be...

摘要：We consider the problem of controlling the precision of the multiple-model multiple-hypothesis filter with Gaussian mixture reduction. The controller adaptively chooses the number of hypotheses kept by the filter to (sub)optimally seek a tradeoff between filter precision and computational effort. In order to quantify the approximation error due to hypotheses truncation, the controller employs probability divergence measures such as f-divergences and the Wasserstein divergence. The proposed sol...

摘要：This article is concerned with the distributed optimal control of multiagent systems (MASs) with general linear dynamics. The cooperative tracking model consisting of multiple followers and one leader is constructed. Distributed optimal controllers are presented using the linear quadratic regulator, which guarantee the leader-following consensus of MASs and the optimization of global performance index. The global information of topology is unneeded for solutions of optimization equations. The ...

摘要：This article introduces novel results on linear coupled differential-difference systems with multiple time-varying delays. First, necessary and sufficient conditions for the positivity and delay-independent asymptotic stability of such systems are introduced. Then, exploiting the internally positive representation technique, we show how such stability results can be systematically exported to non-positive systems of the same class, yielding novel explicit sufficient conditions for their delay-...

摘要：In our previous article, we have considered the supervisory control of the probabilistic discrete event systems (PDESs) under the centralized framework. In this article, we continue to investigate the decentralized probabilistic supervisory control issue of PDESs. The intersection-based control architecture is adopted, and the notion of the probabilistic intersection-based coobservability and its verification algorithm are presented. It is shown that this observability and the probabilistic co...
