摘要:In this article, the robust stability and tracking control of microhand system are researched, wherein the influence of hysteresis characteristics is eliminated, and the tracking accuracy is improved. First, the generalized hysteresis operator is combined with isomorphism to factorize the system, and then controllers are designed to stabilize the hysteretic microhand system. Next, a parallel compensation operator is discussed by combining the right coprime factorization, which eliminates the i...

摘要:Due to the development of bearing-based sensors, the bearing-based localization becomes a typical technology for solving localization problems for multiagent networks. Most of the existing bearing-based network localization methods are developed under a secure environment. In contrast, this article studies a reliable bearing-based network localization problem in an adversarial environment, where some bearing measurements of the agents may be corrupted (which are called the malicious measuremen...

摘要:In this article, we consider the problem of distributed estimation in a sensor network, where multiple sensors are deployed to estimate the state of a linear time-invariant Gaussian system. By losslessly decomposing the Kalman filter, a framework of event-based distributed estimation is developed, where each sensor node runs a local filter using solely its own measurement, alongside with an event-based synchronization algorithm to fuse the neighboring information. One novelty of the proposed f...

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 develops an approach to achieving consensus while improving the dynamic performance for a class of homogeneous multi-agent systems (MASs) using delayed state information via eigenvalue assignment. Note that the distribution of roots of quasi-polynomials plays a fundamental role in the consensus protocol design of the MASs. Some necessary conditions for the distribution of roots for a class of quasi-polynomials are first derived. Then, these conditions are applied to estimate the a...

摘要:This article provides novel results on the infinite-horizon linear quadratic tracking (LQT) problem for continuous-time systems. In order to fulfill optimality for the tracker design, we introduce a new performance index to reformulate the LQT problem in terms of the minimal polynomial of the exosystem that generates the reference trajectory. We prove that, under routine assumptions, the obtained solution to the formulated LQT problem realizes both closed-loop stability and asymptotic tracking...

摘要:In this article, a novel Lyapunov-based approach for strong prescribed-time stabilization by periodic delayed feedback is established. Since the comparison lemma cannot be directly applied to time-delay systems, their proofs rely on trajectory analysis. Based on this approach, a novel control law for strong prescribed-time stabilization of uncertain scalar nonlinear systems is obtained, with the following appealing properties: singularity problems inherent to time-varying high gain approaches ...

摘要:This article presents a novel approach of using convex optimization to solve an optimal control problem with a linear system subject to general nonconvex control constraints and convex state constraints. A convex hull relaxation of the optimal control problem is obtained by taking the convex hull of the original nonconvex control set. To make sure that the convex hull relaxation is exact (which is generally very challenging to achieve), we slightly modify the convex hull relaxation to get an a...

摘要:This article investigates the finite-time distributed H-infinity filtering problem in sensor networks with switching topology and two-channel stochastic attacks. The two-channel stochastic deception attacks are introduced, encompassing network attacks in the communication channel between the model and the sensor, as well as in the channel between the sensors, implemented through an independent Bernoulli process with uncertain probabilities. To address this problem, a novel distributed filter w...
