摘要：This article provides a secure distributed output feedback model predictive control (DOFMPC) solution for the leader-following consensus problems of homogeneous linear disturbed multi-agent systems against multiple cyber attacks. The false data injection (FDI) attacks on the sensor-controller communication channel and denial-of-service (DoS) attacks on the controller-actuator communication channel occur simultaneously. To defend against dual-channel multiple attacks, we propose a secure DOFMPC...

摘要：On the basis of the barrier method, a unified approach for the static output feedback sliding mode control of linear control systems with matched uncertainty is addressed. Without coordinate transformations, a structured static output feedback sliding surface matrix is obtained by solving a constrained minimization problem, and then, a globally stabilizing static output feedback sliding mode controller can be constructed directly. The Lagrange multiplier method is used to derive the necessary ...

摘要：Feedback optimization is a control paradigm that enables physical systems to autonomously reach efficient operating points. Its central idea is to interconnect optimization iterations in a closed loop with the physical plant. Since iterative gradient-based methods are extensively used to achieve optimality, feedback optimization controllers typically require knowledge of the steady-state sensitivity of the plant, which may not be easily accessible in some applications. In contrast, in this art...

摘要：In this note it is shown that the famous multiplier absolute stability test of R. O'Shea, G. Zames, and P. Falb is necessary and sufficient if the set of Lur'e interconnections is lifted to a Kronecker structure. An explicit method to construct the destabilizing static nonlinearity is presented.

摘要：In the context of an event-based control paradigm, when the controller-to-plant channels are subject to event-driven time sampling, a new scheme of feedback model reference adaptive control is developed. The developed scheme can cope with multiple distinct input and state time delays in the dynamics description and mitigate the effect of uncertainties due to both the traditional and network-induced phenomena. The underlying idea is based on a suitable equivalent reformulation of the plant mode...

摘要：Distributed secondary frequency control for power systems, is a problem that has been extensively studied in the literature, and one of its key features is that an additional communication network is required to achieve optimal power allocation. Therefore, being able to provide stability guarantees in the presence of communication delays is an important requirement. Primal-dual and distributed averaging proportional-integral (DAPI) protocols, respectively, are two main control schemes that hav...

摘要：This article investigates the sampled-data sliding-mode control (SMC) problem for a class of uncertain systems with matched disturbances, where the sampling period switches among several different values in a random way and the system state is transmitted to the controller via a fading wireless channel. By applying the coordinate transformation and the input delay techniques, the underlying system with randomly switching sampling period is converted into a certain reduced-order system involvin...

摘要：In this article, we have focused on identifying a class of continuous- and discrete-time multi-agent systems for which a scale-free noncollaborative (i.e., scale-free fully distributed) linear protocol design is developed. We have identified conditions on agent models that enable us to design scalable linear protocols. Moreover, we show that these conditions are necessary if the agents are single input and single output. We also provide a complete design of scalable protocols for this class.

摘要：This article presents an adaptive reference governor (RG) framework for a linear system with matched nonlinear uncertainties that can depend on both time and states, subject to both state and input constraints. The proposed framework leverages an L-1 adaptive controller ( L-1 AC) that compensates for the uncertainties, and provides guaranteed transient performance in terms of uniform bounds on the error between actual states and inputs and those of a nominal (i.e., uncertainty-free) system. Th...

摘要：We study the asymptotic learning rates of belief vectors in a distributed hypothesis testing problem under linear and log-linear combination rules. We show that under both combination strategies, agents are able to learn the truth exponentially fast, with a faster rate under log-linear fusion. We examine the gap between the rates in terms of network connectivity and information diversity. We also provide closed-form expressions for special cases involving federated architectures and exchangeab...
