The smart OGY control method is proposed for two-link rigid robot arm. For this goal the Bifurcation diagram should be applied for acceptable wide range of the input amplitude. Then by using the robot arm in a chaotic amplitude range and Poincare section, the UPO's will be found. After that, the OGY rules are defined for each UPO's and the maximum changed value of amplitude for each UPO's, whic...
The control method of Ott, Grebogi, and Yorke (OGY) is used to stabilize the unstable periodic orbits of a chaotic relay system. Small variations in the height of the relay output are used as control input. The influence of the control activation bound is studied in detail via the one-dimensional Poincaré map of the controlled system. The reduced sensitivity of the multi-step OGY method for hig...
Abstract The generic problem discussed here is the effect of measurement delay on Poincare-based chaos control and possibilities for improved control. When stabilization of unstable periodic orbits or fixed points by the method given by Ott, Grebogi, and Yorke (OGY) must be based on a measurement delayed by tau orbit lengths, the performance of unmodified OGY method is expected to decline. For ...

The control process for a chaotic system as proposed by Ott, Grebogi and Yorke (OGY) is investigated for systems with a one-dimensional Poincaré map. The calculation of the Poinaré map for the controlled system turns out to be an instructive method to analyze the mechanism of OGY control. We introduce the notion of a region of immediate capturing, characterizing the maximum control region that ...

Care of cancer patients may be a source of considerable stress. As part of a large scale longitudinal study of the interaction of biological, psychological and environmental factors in determining patient outcome, the mental and physical health status of 37 members of the nursing staff of a cancer hospital was examined. The study identifies risk factors for stress, professional ‘burn-out’ and p...
