Trush A. The improvement in the quality control system of record-playback information from the magneto-optical media

The object of study: the automatic control of digital information storage using phase-locked loop. The subject of the study - mean-time error quadratic integral estimates, transients caused by changes in the master and the disturbing action using differential constraints. The purpose of the study. Developing ways to improve the system of quality control of digital information storage system with phase-locked by minimizing the mean square error (UPC), the dynamic error of quadratic integral estimates of transients caused by accidental exposure to the setpoint and the disturbing influence on the system. In the thesis, the following research results: - Developed and tested a new method to eliminate conflict between the UPC and minimize the quadratic integral assessment of inherent servo system with the principle of management by exception - have developed a new method for the synthesis of the differential communication tracking systems in accordance with the terms of minimizing the UPC and quadratic integral estimates - a mathematical model autofocus system with a differential head connection which is equivalent to the principle of the combined operation - A mathematical model of primary and synthetic automatic control of digital information storage device coupled to the differential with the interactive system MATLAB. The degree of implementation. The research work of the Institute for Information Recording of NAS associated with focusing of the laser beam in the station records CDs, as well as research work, "Nick KSZI-2", which took data protection authorities of the General Staff of the Center ASU MAT Ukraine.
