SOFTWARE IMPLEMENTATION OF DIGITAL ADAPTIVE STABILIZING LOCAL CONTROL CIRCUITS IN CENTRALIZED APCS
A general solution to the current problem of software synthesis of adaptive digital stabilizing circuits for controlling technological parameters in energy-saving centralized automated process control systems was proposed. The software adaptation problem of the microprocessor regulatory controller (MRC) is solved in the interactive mode by performing three functions: "calibration", "setting", "control". This allows to programmatically create compact, high-speed, object-oriented systems of the local (lower) control level in centralized APCS with minimal costs. The practical use of such an automatic adaptive system for energy-saving control of the thermal regime of the heating method furnace allowed, while reducing the specific fuel consumption by 2%, to increase the average rolling temperature of the billet after the roughing group by 4 °C, while reducing the average energy spent during rolling of each 20-ton continuous billet by 0.02 MW.
