Technical communique: Delay-range-dependent stability for systems with time-varying delay
TL;DR: The present results may improve the existing ones due to a method to estimate the upper bound of the derivative of Lyapunov functional without ignoring some useful terms and the introduction of additional terms into the proposed Lyap unov functional, which take into account the range of delay.
Journal ArticleDOI
Further Improvement of Free-Weighting Matrices Technique for Systems With Time-Varying Delay
TL;DR: A novel method is proposed in this note for stability analysis of systems with a time-varying delay by considering the additional useful terms when estimating the upper bound of the derivative of Lyapunov functionals and introducing the new free-weighting matrices.
Journal ArticleDOI
Analysis and synthesis of networked control systems: A survey of recent advances and challenges.
TL;DR: This paper attempts to present an overview of recent advances and unify them in a framework of network-induced issues such as signal sampling, data quantization, communication delay, packet dropouts, medium access constraints, channel fading and power constraint, and present respective solution approaches to each of these issues.
Journal ArticleDOI
XGBoost Model for Chronic Kidney Disease Diagnosis
Adeola Ogunleye,Qing-Guo Wang +1 more
TL;DR: The set-theory based rule is presented which combines a few feature selection methods with their collective strengths and the reduced model using about a half of the original full features performs better than the models based on individual feature selection method and achieves accuracy, sensitivity, and specificity.
Journal ArticleDOI
An extended reciprocally convex matrix inequality for stability analysis of systems with time-varying delay
TL;DR: An extended reciprocally convex matrix inequality is developed, which reduces the estimation gap of the R CCL-based matrix inequality and reduces the number of decision variables of the recently proposed delay-dependent RCCL.
