ABSTRACT

It is shown that in contrast to open-loop systems peculiarity of automatic control systems with control principle based on deviation (systems with negative feedback) consists in contradiction between conditions of minimality of error and quadratic integral estimate of transient processes on entering its input of one random set-point action. It was ascertained that the minimal value of mean-root square error for these systems is reached for values of their amplification factor for open-loop state close to stability threshold, when slowly decreasing transient processes arise (considerable quadratic integral estimates). We construct recommendations for compromise selection of amplification factor of the tracking system.
