On gain adaptation in adaptive control
The adaptive high-gain output feedback strategy ( ) = ( ) ( ), ( ) ( ) = ( ) is well established in the context of linear, minimum-phase, -input -output systems ( , , ) with the property that spec( ) ; the strategy applied to any such linear system achieves the performance objectives of: 1) global attractivity of the zero state and 2) convergence of the adapting gain to a finite limit. Here, th...
متن کاملAdaptive Gain Control during Human Perceptual Choice
Neural systems adapt to background levels of stimulation. Adaptive gain control has been extensively studied in sensory systems but overlooked in decision-theoretic models. Here, we describe evidence for adaptive gain control during the serial integration of decision-relevant information. Human observers judged the average information provided by a rapid stream of visual events (samples). The i...
متن کاملTwo scale high gain adaptive control
Simple adaptive controllers based on high gain output feedback suffer a lack of robustness with respect to bounded disturbances. Existing modifications achieve boundedness of all solutions but introduce solutions that, even in the absence of disturbances, do not achieve regulation. In this paper a new modification that achieves the desired robustness without the side-effect of undesirable solut...
متن کاملAdaptive contrast gain control and information maximization
Contrast gain control is an important mechanism underlying the visual system’s adaptation to contrast of luminance in varying visual environments. Our previous work showed that the threshold and saturation determine the preferred contrast sensitivity as well as the maximum information coding capacity of the neuronal model. In this report, we investigated the design principles underlying adaptat...
متن کاملAdaptive Gain PID Control for Mechanical Systems
The design and use of PID controllers is a part of what has been denominated Classical Control, which as the name implies, has been studied for many years (DiStefano et al. 1996), however it continues to be a source for research (Alvarez et al. 2008), (Ang et al. 2008), (Su et al. 2010). The structure of the controller contains a differential term to aid in the reduction of system friction and ...
