Синтез и разработка инвариантных систем стабилизации основного вооружения танков

Abstract

The thesis for the degree of candidate of technical sciences, specialty 05.13.03 – Systems and management processes. – National Technical University "Kharkov Polytechnic Institute", Kharkov – 2016. The thesis is dedicated to development analog and digital invariant guidance systems and stabilize the main armament of tanks through the creation of mathematical models perturbed motion tank gun relative to the axis of the pins and the tank tur ret gun relative to the axis of rotation, as well as simulation models of external disturbances acting on the main armament channels vertical and horizontal guidance. It is shown that increasing the degree of invariance closed stabilization system to external perturbations lead to lower stability margin closed system. To maintain the desired stability margin suggested the introduction of the system of additional feedback path for the angular acceleration of the object of stabilization. The features invariant digital stabilization system tank gun, including the need to use a digital low-pass filter Batteruorta and Lanczos filtering high frequency noise output signals of sensors. It is proved that the construction of a digital stabilizer tank cannon appropriate series-parallel use of digital filters Batteruorta and Lanczos. The structure created and the choice of variable constants stabilization algorithms was made that provide an invariance closed system of guidance and stabilization without significantly reducing its stability margin. Modeling of guidance and stabilization in a closed system with subsequent analysis of these processes suggests a significant increase in accuracy working off of external perturbation (at 1.8 – 1.9 times) compared with the standard.
