摘要：Distributed aggregative optimization methods are gaining increased traction due to their ability to address cooperative control and optimization problems, where the objective function of each agent depends not only on its own decision variable but also on the aggregation of other agents' decision variables. Nevertheless, existing distributed aggregative optimization methods implicitly assume all agents to be truthful in information sharing, which can be unrealistic in real-world scenarios, whe...

摘要：A novel model reduction framework for large-scale complex systems is proposed by introducing function -type dynamic control systems via the dimension-keeping semi-tensor product (DK-STP) of matrices. Utilizing bridge matrices, the DK-STP facilitates the construction of an approximate observer-based realization (OR) of a linear control system in the form of a function-type control system, where the functions serve as observers. A necessary and sufficient condition is established for the OR-syst...

摘要：Topology inference for network systems is prominent in many fields. Numerous methods have been proposed to improve the inference accuracy using sufficient observations, but few of them consider the situation where only a limited number of observations are available. This article aims to infer the topology by injecting few excitations into the system and collecting several steps of noisy observations. The problem is challenging because the noise cannot be depressed using several observations, a...

摘要：In this article, we examine the role of stochastic quantizers for privacy preservation in control systems. We first employ a static stochastic quantizer and investigate its privacy-preserving properties regarding the system's initial state. Specifically, we demonstrate that a sufficiently large quantization step guarantees $(0, \delta)$ differential privacy. In addition, the degradation of control performance caused by quantization is evaluated as the tracking error of output regulation. These...

摘要：Networks of agents with logical states, namely Boolean networks, arise in various application domains including biology, computer networks, and social networks. The representation and control of Boolean networks have attracted much attention in recent years. In a parallel line of research, Koopman developed an operator view of nonlinear dynamical systems, which shows that, by making use of observable functions, every nonlinear dynamics can be represented as a (possibly infinite dimensional) li...

摘要：This article presents a design framework of discrete-time regulators for linear port-Hamiltonian boundary control systems. The contribution is twofold. At first, a discrete-time approximation of the plant dynamics originally described by a linear partial differential equation with boundary actuation is introduced. The discretization is performed in time only. Thus, the distributed nature of the state is maintained. Such a system inherits the passivity of the original one and is well-posed, i.e...

摘要：In this article, we study the equilibrium-independent (EI) passivity of a nonlinear electrical power system composed of two-axis synchronous generator models. The model of our interest consists of a feedback interconnection of electromechanical linear and electromagnetic nonlinear subsystems. We mathematically prove the following two results by analyzing the nonlinear subsystem. First, a lossless transmission network is necessary for EI passivity of the electromagnetic subsystem. Second, the c...

摘要：This article considers a distributed adaptive optimization problem, where all agents only have access to their local cost functions with a common unknown parameter, whereas they mean to collaboratively estimate the true parameter and find the optimal solution over a connected network. A general mathematical framework for such a problem has not been studied yet. We aim to provide valuable insights for addressing parameter uncertainty in distributed optimization problems and simultaneously find ...

摘要：This paper investigates the adaptive output feedback resilient control problem for a class of nonlinear cyber-physical systems (CPSs) subject to deception attacks. Here, the CPSs are characterized by unknown nonlinearities that can vary over time, and the attacks can target both the measurement and control communication channels, as well as disrupt the plant dynamics. Utilizing the only measured yet possibly corrupted system output for feedback, we propose a new adaptive resilient control desi...

摘要：This article explores the issue of smooth control of continuous-time switched linear systems. The dual-mode-dependent stabilizing controller is employed instead of the mode-dependent controller used in the existing smooth control results, such that the control freedom is increased and the admissible dual-modal average dwell time switching is generated to enhance the switching frequency of mode-dependent or admissible edge-dependent average dwell-time switching. To eliminate the control input b...
