Идентификация помех, не коррелированных с входным сигналом

Abstract

Considered a retrospective analysis of interference and their localization according to the normal functioning of human-machine systems. Determined by the statistical characteristics of noise, including the expectation and the correlation function. Assumed to be known: impulse response function of the whole system; impulse response function of the object of regulation, where the influence of noise can be neglected; impulse response function of the object in relation to interference; impulse response function of feedback. Proposed a technique for determining the localization of noise characteristics in the annex to the development of flight simulators. Is given an algorithm for determining noise characteristics. It includes identification of a number of transfer functions from the equations of dynamics; determination of the spectral densities of noise in different nodal points. The method was tested in the development of specific ergatic systems (transport simulators for training operators).

Рассматривается ретроспективный анализ помех и их локализация по данным нормального функционирования человеко-машинной системы. Определяются статистические характеристики помехи, в том числе математическое ожидание и корреляционная функция. Предполагаются известными: импульсная переходная функция всей системы; импульсная переходная функция части объекта регулирования, где действием помех можно пренебречь; импульсная переходная функция объекта по отношению к помехе; импульсная переходная функция обратной связи. Приводятся методики для определения локализации помехи и их характеристик в приложении к разработке авиационных тренажеров. Предлагается алгоритм для определения характеристик помехи. Он включает определение ряда передаточных функций по уравнениям динамики, по которым находятся спектральные плотности помехи в различных узловых точках. Методика апробирована при разработке конкретных эргатических систем.
