Narozhnyj V. Support of active fault tolerance of the modified onboard measuring device.

Object of investigation - onboard measuring device оf control systems. The purpose of work is to develop tools and algorithms of deep diagnosis and flexible restoration of measurements for support of active fault tolerance of the modified onboard measuring device. Methods of researches: empirical researches - observation, measurements and experiment; empirical and theoretical levels of the research - abstragation, analysis and synthesis, induction and deduction, modeling; theoretical researches - idealization, formalization, hypothesis and supposition. Scientific value of dissertation outcomes. The elaborated structure of inertial and uninertial onboard measuring device, and the way of it's use, diagnostic support of the modified onboard measuring devices and mathematical, algorithmic support of flexible restoration of measurements are further development of the theory of technical diagnostics and fault tolerance of onboard control systems with reference to onboard measuring devices. The practical valu e of dissertation outcomes consists: in increasing of average time between failures of onboard measuring devices in 1,25-1,67 times, while supporting them of property of active fault tolerance with a possibility of this index raise up to 2 times; in reducing of mass and power expenditures of modified onboard measuring devices in 1,1-1.5 times of rather then onboard measuring devices constructed on a majority principle. The practical value of dissertation work outcomes is confirmed by the acts of inculcation: in Kharkov instrument-making design office "Aviacontrol" from 21.01.99; in the State small enterprise "CIIТ" from 8.10.99; in educational process of State aerospace university named by N.E. Zhukovsky "Kharkov aviation institute" from 30.11.99.
