Adaptive optics with adaptive filtering and control
Proceedings of the 2004 American Control Conference, 2004This paper presents a quasi adaptive control method for adaptive optics. Adaptive compensation is needed in many adaptive optics applications because wind velocities and the strength of atmospheric turbulence can change rapidly, rendering any fixed-gain reconstruction algorithm far from optimal.

Abstract In this paper, an Expert-Adapt ive PID Controller is developed. The SelfTuning st rategies are based on on-line pattern recognition and PID self-tuning knowledge-base. The knowledge-base is constructed with the interior relations between patterns of control curves and PID parameters. Also some important control experiences are built into the

On the Applicability of Adaptive Control
IFAC Proceedings Volumes, 1987Abstract In the last decade there has been a growing awareness that adaptive control can produce improved performance in real application, mainly as a result of considerable advances in the understanding of adaptive control theory as well as in the computer technology.

Adaptive control of systems with backlash
Automatica, 1992Abstract We develop a mathematical model of backlash inverse and give a parametrization of the error caused by its estimate. We then design an adaptive backlash inverse controller for unknown plants with backlash and show the global boundedness of the dosed-loop signals. Simulations show major improvements of system performance.

Adaptive AIMD congestion control
Proceedings of the twenty-second annual symposium on Principles of distributed computing, 2003The main objectives of a congestion control algorithm are high bandwidth utilization, fairness and responsiveness in changing environment. However, these objectives are contradicting in particular situations since the algorithm has to constantly probe available bandwidth, which may affect its stability.

Adaptive Decentralized Control.
1984Abstract : This Final Report summarizes the results of a research effort directed towards the development of adaptive decentralized control systems. The adaptive controller in such a system must operate in the presence of unmodeled dynamics. An input-output approach was developed for analyzing the global stability and robustness properties of adaptive ...

The Adaptive Control of Prehension
Canadian Journal of Physiology and Pharmacology, 1994This paper provides a brief overview of the adaptive control of prehension. Several primary issues for research in the field are considered. One pertains to the stages of prehensile activity, with particular concern for the kinematic control of pre-contact phases, and the coordination of load and grip forces following contact.

IEEE Transactions on Man Machine Systems, 1969
Experimental studies and control descriptions of the human operator in recent years have extended the knowledge of adaptive behaviour in manual control from vague generalities about his versatility to quantitative descriptions. Considerable data have been gathered on the ability of the human to adapt to changes in input spectra, controlled element gain,

Adaptive Control of a Synchronous Generator
IFAC Proceedings Volumes, 1983Abstract Theoretical aspects are based on PARK's equations while the experimental part is achieved from on-line machine frequency responses on small signals for different active or reactive powers. The concordant results show that a third order multi-input-multi-output non minimum phase system characterizes correctly the dynamic behaviour of the ...
