摘要：We discuss the role of monotonicity in enabling numerically tractable modular control design for networked nonlinear systems. We first show that the variational systems of monotone systems can be embedded into positive systems. Utilizing this embedding, we show how to solve a network stabilization problem by enforcing monotonicity and exponential dissipativity of the network subcomponents. Such modular approach leads to a design algorithm based on a sequence of linear programming problems.

摘要：In this article, we consider supervisory control of stochastic discrete event systems (SDESs) under linear temporal logic specifications. Applying the bounded synthesis, we reduce the supervisory synthesis to the problem of satisfying a safety condition. First, we consider a directed controller that allows at most one controllable event to be enabled. We assign a negative reward to the unsafe states and introduce an expected return with a state-dependent discount factor. We compute a winning r...

摘要：In this article, we study the performance of the gradient play algorithm for stochastic games (SGs), where each agent tries to maximize its own total discounted reward by making decisions independently based on current state information, which is shared between agents. Policies are directly parameterized by the probability of choosing a certain action at a given state. We show that Nash equilibria (NEs) and first-order stationary policies are equivalent in this setting, and give a local conver...

摘要：In this article, we study the problem of distributed estimation of discrete-time LTI systems with bounded noise against sparse integrity attacks. A malicious adversary can corrupt an unknown set with $p$ out of $m$ sensors and manipulate their observations arbitrarily. We propose a general secure estimation framework by decomposing a centralized linear observer into local ones and fusing the local estimates by minimizing specially designed convex functions. The optimization problem can be solv...

摘要：The coupled Riccati equations (CREs) are a set of multiple Riccati-like equations whose solutions are coupled with each other through matrix means. They are a fundamental mathematical tool to depict the inherent dynamics of many complex systems, including Markovian systems or multiagent systems. This article investigates a new kind of CREs called harmonic-CREs (HCREs), whose solutions are coupled using harmonic means. We first introduce the specific form of HCREs and then analyze the existence...

摘要：In this article, we consider the problem of estimating the generalized cepstral coefficients of a stationary stochastic process or stationary multidimensional random field. It turns out that a naive version of the periodogram-based estimator for the generalized cepstral coefficients is not consistent. We propose a consistent estimator for those coefficients. Moreover, we show that the latter can be used in order to build a consistent estimator for a particular class of cascade linear stochasti...

摘要：In this article, we investigate and derive optimal strategies for the pursuit-evasion problem of two players with damped double integrator dynamics. The pursuer is assumed to have a greater acceleration and attempt to capture the evader as quickly as possible, while the evader wants to avoid or delay the capture. Different from the problems with single integrator dynamics, optimal strategies for such a problem are not intuitive. To solve this problem, we exploit both geometrical methods and di...

摘要：In this article, we introduce novel duality relations that complement the well-known invariant ellipsoids method. These relations yield ellipsoids with newly established geometrical interpretations and connections to linear system norms. The established duality leads to the optimal synthesis results for state-feedback control, filtering, and output-feedback control problems in the presence of bounded disturbances. The proposed output-feedback control solution is demonstrated to be optimal and ...

摘要：This article focuses on the consensus and tracking problem of nonlinear multiagent systems under communication delays, and proposes a distributed predictive control scheme, which is independent of the system model and able to actively compensate for communication delays. First, a consensus-related auxiliary variable and its corresponding estimator are innovatively designed to provide a globally consistent value. Then, the idea of dynamic linearization is adopted to obtain the equivalent linear...

摘要：This article studies distributed online bandit learning of generalized Nash equilibria for online games, where the cost functions of all players and coupled constraints are time-varying. The function values, rather than full information about cost and local constraint functions, are revealed to local players with time delays. The goal of each player is to selfishly minimize its own cost function with no future information, subject to a strategy set constraint and time-varying coupled inequalit...
