This scientific paper considers the process of improving the quality of products made of polymeric materials by means of the effect of high-frequency radiation on the object of control and the detection of defects of various kinds and nature in an automated mode. The authors of the article present the range of products made of polymer composite materials used in the new-generation rolling stock, address the issue of non-destructive testing and improving the performance properties of parts in the modern production process, and give the grounds for choosing the high-frequency diagnostic method as the most suitable for improving quality manufacturing and during repair work. This article describes the development of an automated process control system for high-frequency control on an industrial scale. Research and development of the automation system is carried out on the basis of a device for diagnosing high-frequency currents, which was developed and patented by the authors as part of this study. The article provides a method for determining the input diagnostic parameters. Also, the work presents flowcharts of the control process monitoring algorithm when performing preparatory operations and directly when detecting defects such as "air inclusion", "moisture content", "metal inclusion". The acclimatization mode is described. The operation of the blocks of the phase state control mode and the mode of control of the dynamics of the inception of partial discharges is explained. The article touches upon the problem of restoring the operational properties of products and improving quality in an automated mode on completing of the diagnostic process. The authors present the sequence of operation of the information processing unit, describe the completion of the management system shutdown, and provide conclusions.
