Lysytsya P. Adaptive control by quartz tubes making process

Dissertation is devoted to upgrading of quartz tube geometry forming process by creation of the adaptive control system. Research of unstationary process of forming the geometry of quartz tube from a block has been carried out. The necessity of maintaining the balance of glass mass in the zone of the forming of the tube from a block has been proved in such process control. The spatio-temporal and standard models were built for this purpose. The four-level adaptive system with standard model has been synthesized and tested for its optimization. Such system provides the fixed removal of glass mass and compensates the delay, which appears at measuring of diameters of the formed tube. Hardware, software and basic subsystems of the complex have been designed. Its significant advantage over the existing facilities is proven by studying the hardware and software characteristics.
