Controlling on-off intermittent dynamics

Physical Review E, 1996
On-off intermittent chaotic behavior occurs in physical systems with symmetry. The phenomenon refers to the situation where one or more physical variables exhibit two distinct states in their time evolution. One is the ``off'' state where the physical variables remain constant, and the other is the ``on'' state where the variables temporarily burst out

Robustness and Trade-offs in Repetitive Control

Automatica, 1998
The authors consider robust repetitive control in the sense of asymptotic rejection or attenuation of periodic disturbances or tracking periodic references. They also provide a detailed example of a compact disc player.

Modélisation et contrôle d'un véhicule tout-terrain à deux trains directeurs. (Modelling and control of four-wheel-steering off-road vehicle)

, 2021
L'intérêt pour les véhicules autonomes n'a cessé de croître ces dernières années. La conduite autonome sur des terrains accidentés, ou encore avec des conditions d'adhérences faibles sont encore des défis technologiques à relever.

Neuronal ‘On’ and ‘Off’ signals control microglia

Trends in Neurosciences, 2007
Recent findings indicate that neurons are not merely passive targets of microglia but rather control microglial activity. The variety of different signals that neurons use to control microglia can be divided into two categories: 'Off' signals constitutively keep microglia in their resting state and antagonize proinflammatory activity.

Trade-Offs in Robust Controller Design

1992 American Control Conference, 1992
Structured singular value paradigm is used to present a method that helps the control designer assess the relative importance of information regarding the feedback system. Such information consists of process knowledge through the model, control system complexity quantified by the controller order and performance requirements as set forth by the ...
