Experimental identification of the process of heating semifinished products on an MCVD lathe

This articles examines the use of the process of identification for the study of different objects and subsequent system automation. Modified chemical vapor deposition (MCVD) is discussed as an illustration of a process that can be automated with the use of parametric identification, and the transfer function of this process is obtained. The operation of heating semifinished products on an MCVD lathe is examined as a specific example. The MCVD method makes it possible to obtain semifinished products for drawing optical fibers and is based on the deposition of oxides of silicon on the inside surface of a glass tube by thermophoresis. The tube subsequently vitrifies and “collapses” into the rod/semifinished product . Transient response curves are obtained during the experiment and averaged for use in parametric identification. The transfer function of the automation object is also obtained.
