Vdovitchenko O. Methods and technologies of human-centered personal computers adaptive power control

The aim of the study is to reduce the energy consumption of PCs under condition of preservation of acceptable performances for it's using. The object of study is the process of PC's power management. Subject of research is mathematical models and methods of power management. Methods of research. We use the set theory, the theory of Markov models, theory of mathematical statistics, theory of adaptive systems, methods of physical and mathematical experiments and methods of object-oriented analysis and design. The scientific novelty of the work is - for the first time a stochastic model of the computer system which is based on the user's computer adaptive power control is developed; - the method of parametric identification of the hidden Markov model of adaptive systems PC power management is improved; - an information technology of user-oriented adaptive control PC power consumption in terms of collection and preliminary processing of data, creating models and methods of model's identification and adaptive control of PC's power consumption has been further developed. The practical significance of the results. The main provisions of the thesis research are implemented in the form of engineering algorithms and corresponding software tools, which are the part of the information technology of oriented on the user of personal computer's adaptive power management. The aforecited model and method have been pilot-tested, making it possible to evaluate the accuracy and reliability of model and the effectiveness of the proposed method. The practical method's implementation of PC's adaptive power management was tested during the development of software's prototype of adaptive management of PC's power consumption. Using the developed information technology contributes to solving the problem of the of the modern energy-efficient PCs' using. The results of the thesis are introduced: - in Sigma Software Company; - the National Aerospace University "KhAI". Application area is the PC power management.
