Analysis of the accuracy of the automatic stabilization of the speed of the electric drive with random disturbances.

Abstract

A method for analyzing the accuracy of the electric drive speed stabilization systems when exposed to random disturbances with a wide spectrum based on an integral quadratic criterion is proposed. The criterion allows obtaining analytical expressions for comparative analysis of various schemes whose frequency characteristics are described by fractional rational expressions without substituting the numerical values ??of parameters. and multi-circuit electric drive control systems with direct current motors Depending independent vozbuzhdeniya.Polucheny for selecting parameter values ??for which the best accuracy is achieved.
