AN APPROACH TO MODELING STATIONARY NOISE IN THE MEASUREMENT CHANNELS OF AUTOMATIC CONTROL SYSTEMS

Modeling of noise in the measurement channels becomes essential in research of processes in automatic control systems as data-driven systems. In the paper we consider the approach to researching and modeling the stationary noise with arbitrary characteristics and characteristics derived from the analysis of real signals of noise. The noise model is represented as a sum of additive components with the possibility of further analysis.

Keywords: stationary noise, decomposition, modeling, frequency spectrum, amplitude distribution, algorithm, software, Matlab / Simulink.
