Разработка цифровой системы стабилизации поля зрения прибора наблюдения наземного подвижного объекта

Abstract

Thesis for the of Candidate of technical sciences, Specialty 05.13.03-System and management processes. – National Technical University "Kharkiv Polytechnic Institute", Kharkiv,2015. Aim of the thesis is to develop a digital system of stabilization of the visual field of extended precision observation instrument of surface-mobile object. Proved the necessity of conversion from the power type systems of stabilization to the indicator type systems of stabilization with digital electronic unit. High interference immunity of the indicator type system can be achieved by the using of digital electronic block of digital low-frequency filter, including filters of Batteruuort and Lanzrosh with series-parallel connection. Considered the possibility of its using in the algorithms, which are implemented by the digital electron block, principles of strapdown inertial system in which the angle of divergence between the laser beam of range unit sight and direction to the target is not measured but calculated by using kinematic formulas relative the orientation quaternion parameters. Established that the stabilizer built on these principles provides 2÷3 times higher accuracy compared to the power type stabilizer.
