A functional and equivalent structural scheme of the control system of the carding machine is proposed. The frequency characteristics of the automatic control system are built, the stability of the system is revealed. To determine the stability of the system, the amplitude-phase Nyquist stability criterion was used. The investigation of the stability of the automatic control system of carding machine carried on a logarithmic amplitude and phase frequency characteristics. The results of the study indicate a stable state of the automatic control system.<\/em><\/p>\n<p>&nbsp;<\/p>\n<h4><strong><em>Key words<\/em><\/strong><\/h4>\n<p>&nbsp;<\/p>\n<p><em>\u00a0carding machines, DC motors, thyristor converter, tape density, PI controller, frequency characteristics<\/em><\/p>\n<p>&nbsp;<\/p>\n<h4><strong><em>References<\/em><\/strong><\/h4>\n<p>&nbsp;<\/p>\n<ol>\n<li><em> Avrorov V.A., Kivshenko A.M.
