This report results from a contract tasking Institute of Mathematical Machines and Systems as follows Main target of research are dynamic recurrent neural networks and their application for adaptive control of complicated dynamical systems. Recurrent neural networks, unlike classical methods, dont require full a priori information about properties of controlled object. So their use allows to achieve high precision and reliability for control of complicated dynamical objects in conditions of lack of information about internal state of the object. Distinctive feature of researched in this project recurrent neural networks is the use of dynamical neurons, that are able to forget9559 outdated information, and multimodular architecture, that allows to flexibly combine adaptation for changing environment properties and features of associative memory that keeps different controlled objects models. Neural associative memory is able to recognize large-scale changes of environment conditions, that allows to reconfigure networks structure in real time for more efficient control. Project includes the critical review of publications in the given area, theoretical research of training methods of dynamical recurrent neural networks, methods of reconfiguration of such networks, decomposition of neurocontrolling task, and experimental test of achieved theoretical results, that will be performed on MNN CAD with the use of specially developed models of RNN and controlled objects.
