Industrial Automatic Control Systems and Controllers Annotation << Back Adaptive Control of the Effi ciency of the Upper Part of the Distillation Unit Shevchuk V.P. A method of adaptive control of the effi ciency of the functioning of the top of the distillation unit is proposed. To implement the adaptive control method, the following are proposed: an algorithm for determining the drift rate of the control criterion; an algorithm for visualizing the effi ciency of the upper part of the distillation unit; an algorithm for visualizing the effi ciency of the upper part of the distillation unit. Modeling of control processes, measurement processes and processes of formation of control actions has shown the operability and effectiveness of all proposed algorithms. The relative error of modeling the control process, according to the proposed method, is less 2·10–2 %. Modeling of the processes of formation of the relative methodological dynamic error of measuring information processing shows that the main tuning coeffi cients of the monitoring systems software should be considered the interval of the current identifi cation of the mathematical model, since it connects the measurement time of a physical quantity, as the tuning coeffi cient of the analog input module, with the polling period of sensors, as the tuning coeffi cient of the analog output module. It is these tuning coeffi cients that determine the lengths of arrays, both for the operation of pre-fi ltering, linearization and visualization algorithms, and for optimization algorithms, and, ultimately, for algorithms for evaluating the metrological characteristics of monitoring systems. Keywords: metrology of monitoring systems, equation of measurement of the control criterion, software setup, able to work of the control algorithm, effi ciency of the control algorithm.
