Journal ArticleDOI
Stabilization of positive switched systems with time-varying delays under asynchronous switching
TL;DR: This paper investigates the state feedback stabilization problem for a class of positive switched systems with time-varying delays under asynchronous switching in the frameworks of continuous-time and discrete-time dynamics by constructing an appropriate co-positive type Lyapunov-Krasovskii functional.
Journal ArticleDOI
Development of lumped-parameter mathematical models for a vehicle localized impact
TL;DR: In this paper, a method of modeling for vehicle crash systems based on viscous and elastic properties of the materials is proposed, which is suitable for localized collisions simulation. But it is not suitable for simulation of vehicle-to-pole collisions.
Journal ArticleDOI
Mathematical modeling of a vehicle crash test based on elasto-plastic unloading scenarios of spring-mass models.
TL;DR: In this paper, the usability of spring which exhibit nonlinear force-deflection characteristic in the area of mathematical modeling of vehicle crash is investigated. And the authors present a method which allows them to obtain parameters of the spring-mass model basing on the full-scale experimental data analysis.
Journal ArticleDOI
Disturbance tolerance and rejection of discrete switched systems with time-varying delay and saturating actuator
TL;DR: In this article, a sufficient condition for the existence of a state feedback controller is proposed such that the disturbance tolerance capability of the closed-loop system is ensured by solving a convex optimization problem with linear matrix inequality (LMI) constraints.
Journal ArticleDOI
New approaches to positive observer design for discrete-time positive linear systems
TL;DR: An efficient positive observer design approach is proposed by using linear programming such that the observer error system is exponentially stable and an interval observer design is proposed for uncertain positive systems.
