Neural Network‐Based Runtime Monitoring and Control for Unknown Nonlinear Systems
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Real‐time system monitoring and stabilization become especially challenging when the system dynamics are unknown. This article introduces a novel design for monitoring and stabilizing unknown nonlinear systems with measurement noise. The design utilizes a generic modelling framework by decomposing the system into a known tunable linear ...

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Data-driven design of structured sparse feedback controllers
SICE Journal of Control, Measurement, and System IntegrationThis article proposes a data-driven design method of structured sparse feedback controllers. In situations where the system model is unavailable but the measurement data are available, we address the problem of finding a feedback controller which ...

Sustainable Development, EarlyView.ABSTRACT South Africa faces persistently high poverty and inequality alongside a highly concentrated economic structure, raising questions about whether merger control, especially public‐interest provisions, can contribute to poverty reduction. However, empirical evidence directly linking merger adjudication outcomes to poverty remains limited.

OBSERVER BASED H ∞ CONTROLLER DESIGN: AN LMI METHOD [PDF]
, 1999 观测器型控制器由于其结构简单和物理意义明确而受到广泛重视.在假定控制器为一般的动态补偿器情况下，利用lMI技术解H∞控制器使得未知参数较多且求取过程复杂.现利用lMI技术研究观测器型H∞控制器，则控制器参数可通过三个lMI即可获得，这个lMI组的适定性问题用现有的工具软件即可确定.Observer based controller is widely accepted for its simple structure and explicit physical meaning.But the ...
