Sampled-data control for a class of linear systems with randomly occurring missing data

open access: yes, 2023
© Springer International Publishing AG, part of Springer Nature 2019. In this chapter, design methods of the sampled-data control under missing data for dynamics systems have been developed. Two models of discontinuous sampled-data control signals in the

Detecting dominant changes in irregularly sampled multivariate water quality data sets [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Time series of groundwater and stream water quality often exhibit substantial temporal and spatial variability, whereas typical existing monitoring data sets, e.g.

Sampled-Data Control of Singular Systems with Time Delays

open access: yesAbstract and Applied Analysis, 2014
This paper is concerned with sampled-data controller design for singular systems with time delay. It is assumed that the sampling periods are arbitrarily varying but bounded.

Novel Equalities for Stability Analysis of Asynchronous Sampled-Data Systems

open access: yesIEEE Access, 2020
This paper is concerned with the stability analysis problems of asynchronous sampled-data systems with use of a input-delay approach, where a sampled-data system can be reformulated into a time-delay system having incremental delays.

Malicious traffic detection on sampled network flow data with novelty-detection-based models

open access: yesScientific Reports, 2023
Cyber-attacks are a major problem for users, businesses, and institutions. Classical anomaly detection techniques can detect malicious traffic generated in a cyber-attack by analyzing individual network packets. However, routers that manage large traffic

Synchronization of Coupled Harmonic Oscillators Using Quantized Sampled Position Data

open access: yesJournal of Control Science and Engineering, 2017
For coupled harmonic oscillators (CHO), the paper studies the synchronization problem by using the quantized current sampled position data. The logarithmic quantizer is adopted here to quantize the information transmitted; thus the quantization error of ...

Iterative learning control with sampled-data feedback for robot manipulators

open access: yesArchives of Control Sciences, 2014
This paper deals with the improvement of the stability of sampled-data (SD) feedback control for nonlinear multiple-input multiple-output time varying systems, such as robotic manipulators, by incorporating an off-line model based nonlinear iterative ...
