In this manuscript, model predictive control for class of discrete fuzzy large-scale systems subjected to bounded time-varying delay and disturbances is studied. The considered method is Razumikhin for time-varying delay large-scale systems, in which it includes a Lyapunov function associated with the original non-augmented state space of system dynamics in comparison with the Krasovskii method.

Este artículo diseña un sistema de control para el problema de seguimiento de trayectorias de un vehículo quadrotor con una carga suspendida desconocida. La presencia de esta carga desconocida incrementa considerablemente la complejidad del problema, y su oscilación actúa como una perturbación incierta que afecta a la dinámica propia del vehículo. [...]
This article designs a control system for the trajectory tracking problem of a quadrotor vehicle with an unknown suspended load. The presence of this unknown load considerably increases the complexity of the problem while its oscillation acts as an unknown perturbation that affects the dynamics of the vehicle. [...]

Some techniques for studying the existence of limit cycles for smooth differential systems are extended to continuous piecewise linear differential systems. Rigorous new results are provided on the existence of two limit cycles surrounding the equilibrium point at the origin for systems with three zones separated by two parallel straight lines without symmetry.

9.7 MB Smart Traffic Control for the Era of Autonomous Driving / Qiao, Jianglin ; de Jonge, Dave, dir. ; Zhang, Dongmo, dir. ; Sierra Garcia, Carlos Alberto, dir.
En l'última dècada, la investigació sobre vehicles autònoms (AV) ha fet un progrés revolucionari. Els avenços en intel·ligència artificial (IA), i especialment en aprenentatge automàtic, permeten que els cotxes autònoms aprenguin a resoldre situacions complexes basant-se en dades de milions d'hores de conducció acumulades, molt més del que podria arribar a fer qualsevol conductor humà.
