Suppression of random noise by the separation of frequencies

TL;DR

This paper identifies contradictions in existing theories of random stationary processes and introduces a new noise suppression method that improves the identification of dynamic characteristics in control systems, demonstrated on aircraft pitch control.

Contribution

It presents a novel approach to noise suppression based on frequency separation, enabling better identification of system dynamics in multidimensional linear models.

Findings

Contradictions in classical theory of stationary processes are demonstrated.

A new noise suppression method based on frequency separation is proposed.

An algorithm for aircraft pitch control considering structural deformation is developed.

Abstract

It is shown that a well-known theory of random stationary processes contain contradictions. Integral representations of correlation functions and random stationary processes are investigated further. The new method of struggle with handicaps is received on the basis of the carried out researches. Method of dealing with noise leads to a new method of identification of dynamic characteristics of control objects in a class of multidimensional linear stationary models. As an example, describe an algorithm for obtaining the differential equation-wire feed control aircraft pitch, taking into account the elastic deformation of the structure of class IL -96 aircraft.
