摘要：This article aims at collaborative optimization of sum of convex functions over networks subject to globally coupled affine equality and inequality constraints whose partial information is known by each agent. The proposed discrete-time fully parallel distributed algorithm is the first of its kind in the sense that it does not require diminishing step size, (sub)gradient, and/or solving a subproblem at each time step. The algorithm is able to converge to an optimal solution for any local conve...

摘要：In this work, we develop a scheme for constructing continuous approximations (referred to as abstractions) of a class of discrete-time control systems with partially unknown dynamics. The abstraction, itself a nonlinear discrete-time control system (preferably with a significantly lower dimension than the original one) can be used as a substitute in the controller design process. The technique consists of using data sampled from the concrete system to find a lower dimensional subspace of its s...

摘要：We present a general framework for solving the problem of Nash equilibrium (NE) seeking with LTI agents subject to constant external disturbances. The framework consists of breaking down the design using a four-part control methodology. Using this methodology, we show that the problem is reduced to the design of a set of decentralized stabilizing controllers. We present one potential controller design using tools from passivity theory. Finally, we show the applicability of the framework throug...

摘要：This article considers quantized feedback control of discrete-time linear systems involving quantizations and saturations of the system input and state. A new representation of saturation map is presented by equality with bounded uncertain diagonal matrix and reduces conservatism. Further, based on spherical polar coordinate quantizer, the quantization error is converted to sector-bound uncertainty. Thus, the considered system is modeled as uncertain system and the considered problems are conv...

摘要：Networked systems must often balance privacy in avoiding leaking sensitive information, with utility in communicating the information that is needed by components to operate correctly. We consider the problem of enforcing privacy and utility with both obfuscation (altering communications to mislead eavesdroppers) and control (restricting system behavior to avoid information leakage). We present a formulation of this problem that models components of the networked system as interconnected react...

摘要：The purpose of this note is to extend the approximate dynamic programming (ADP) method to the infinite time stochastic optimal control (ergodic) problem. It is also shown that a modification of the basic algorithm solves the output feedback problem. The ADP solution of the ergodic problem differs in significant ways from its deterministic counterpart.

摘要：In this article, we establish that stabilization of a class of linear, hyperbolic partial differential equations (PDEs) with a large (nevertheless finite) number of components, can be achieved via employment of a backstepping-based control law, which is constructed for stabilization of a continuum version (i.e., as the number of components tends to infinity) of the PDE system. This is achieved by proving that the exact backstepping kernels, constructed for stabilization of the large-scale syst...

摘要：In this article, we study the privacy-preserving distributed optimization problem, aiming to prevent attackers from stealing the private information of agents. For this purpose, we propose a novel privacy-preserving algorithm based on the Advanced Encryption Standard, which is both secure and computationally efficient. By appropriately constructing the underlying weight matrices, our algorithm can be applied to time-varying directed networks. We show that the proposed algorithm can protect an ...

摘要：This article investigates the finite-horizon distributionally robust mixed-integer control (DRMIC) of uncertain linear systems. However, deriving an optimal causal feedback control policy for this DRMIC problem is computationally formidable for most ambiguity sets. To address the computational challenge, we propose a novel distributionally robust lifted control policy (DR-LCP) method to derive a high-quality approximate solution to this DRMIC problem for a rich class of Wasserstein metric-base...

摘要：Denial-of-service (DoS) attacks impose an important threat for networked switched systems, as they impede the effective transmission of the control signals and measurement data and disrupt the synchronization of the switching modes between the controllers and the plant. To address this challenge, this article proposes a sliding-mode controller design for safety against DoS attacks in networked switched systems. First, we analyze the impact of the time delays induced by signal quantization and ...
