Active control of chaotic signals in elektronic systems

Unlike the useage of everyday language the concept of chaos uses in the meaning that ?irregularity in order ? in science. There is pretty important difference between use of everyday language and use of scientific.Chaos is interpreted that irregular unpredictable behavior of complex ,nonlineear dynamic systems.In theory,everything that occur according to the time in practice for example pollen production, population growth, economic changes , world ice field etc. may be chaotic.Chaos theory has a various important usage that stock market, meteorology ,communication, medicine, mecenic, chemistry, biology, economy. Studies are chaotic. in areas such as physics, chemistry, mathematics, physiology, sociology, economics, history, ecology, astronomy, hydraulics, atmospheric, international relations, solar systems, engineering.There are many successful and widely usage of chaos that in fields such as power systems, high-performance circuits and devices, information technology, liquid mixing with low energy consumption, to prevent the collapse of power systems, increasing the power of lasers, electronic circuits to synchronize the outputs, oscillating chemical reactions, control, examination of brain waves, image compression and transmission, automatic control systems, secure communications, laser physics, and financial modeling.This thesis aims are examining the science of chaos and works of the science of chaos until the present day, investigating the areas of chaos that used in, introducing chaotic systems, making a simulation of chaotic circuit models on Matlab and searching the systems behaviours, examining and introducing active control method and synchronization and in this direction ensuring the synchronization between two chaotic systems by applying the active control.In this thesis, synchronization is introduced and examined methods of synchronization, active control method that recognized as the large-scale effective technique is investigated for synchronization. In this direction Rucklidge chaotic system is examined and the synchronization is ensured between two chaotic systems by applying the active control. The system behavior were examined before and after the control.
