Nature Communications, 2020 Bacterial chemoreceptors have multiple methylation sites, but whether the order of methylation matters is unclear. Here, the authors show that sequentially ordered methylation is critical for perfect adaptation and for attenuating the trade-off between ...

Analysis and Design of Full-Order Flux Observers for Sensorless Induction Motors [PDF]
, 2004 This paper deals with the flux estimation for sensorless induction motor drives. The linearized model of the speedadaptive full-order flux observer is applied to help choosing the observer gain and the speed-adaptation gains.

A robust adaptive robot controller [PDF]
, 1992 A globally convergent adaptive control scheme for robot motion control with the following features is proposed. First, the adaptation law possesses enhanced robustness with respect to noisy velocity measurements.

The generalized super‐twisting algorithm with adaptive gains [PDF]
International Journal of Robust and Nonlinear Control, 2020 AbstractIn this article, a novel adaptive generalized super‐twisting algorithm (GSTA) is proposed for a class of systems whose perturbations and uncertain control coefficients may depend on both time and state. The proposed approach uses dynamically adapted control gains, and it is proven that this ensures global finite‐time convergence.

Robust gain scheduling techniques for adaptive control [PDF]
2009 European Control Conference (ECC), 2009 Robust and gain-scheduling analysis and design techniques are used to realize an adaptive controller. LFT representations of the plant and controller are used so that the stability and performance properties of the adaptive scheme can be studied off-line, and the on-line computational time for implementing the LFT controller is reduced. This controller

Pushing it to the Limit: Adaptation with Dynamically Switching Gain Control
EURASIP Journal on Advances in Signal Processing, 2007 With this paper we propose a model to simulate the functional aspects of light adaptation in retinal photoreceptors. Our model, however, does not link specific stages to the detailed molecular processes which are thought to mediate adaptation in real ...

Contrast Gain Reduction in Fly Motion Adaptation [PDF]
Neuron, 2000 In many species, including humans, exposure to high image velocities induces motion adaptation, but the neural mechanisms are unclear. We have isolated two mechanisms that act on directionally selective motion-sensitive neurons in the fly's visual system. Both are driven strongly by movement and weakly, if at all, by flicker.

Efficacy of spaced learning in adaptation of optokinetic response
Brain and Behavior, 2021 Introduction The superiority of spaced training, in which repeated training sessions are given with resting intervals, over massed training in learning efficacy has been well established.

Suboptimal eye movements for seeing fine details. [PDF]
, 2018 Human eyes are never stable, even during attempts of maintaining gaze on a visual target. Considering transient response characteristics of retinal ganglion cells, a certain amount of motion of the eyes is required to efficiently encode information and ...
