STATISTICAL METHODS OF ESTIMATING THE RESPONSE OF AUTOMATIC SYSTEM ON CONTROL COMMANDS

A. K. Ablesimov, L. V. Pohribniak

Abstract


It was established the impossibility to estimate the reaction of automatic control systems on typical signals and also to disallowed only take into account the quality rates. The results of theoretical and experimental research showed, that control signals are random. For the purpose of estimating influences of these signals, it is necessary to use statistical methods to evaluate the response of the automatic control system on operator commands. It is considered the method of estimating the accuracy of automatic control systems that operates in modes of stable guidance at random disturbing influences and control signals.
