Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Development multiply autonomous digital control system insensitive V.S. KUDRYASHOV S.V. RYAZANTSEV D.A. SVIRIDOV This article deals with the problem of multi-loop non-stationary objects regulation. It is noted that one of the most effective ways of these objects control is to use autonomous digital control systems of low sensitivity. The purpose of this paper is to develop a specific approach to the synthesis of such systems and to study its effectiveness. It has been proposed a method of multi-loop object coverage with negative feedbacks containing corrective links that provide the object dynamic characteristics constancy in the conditions of its model parameters variation in possible determined ranges. A special attention is paid to the development of a method of the correcting links synthesis, calculated on the base of the sensitivity functions. It has been given calculation of regulation system unit control, which is carried out on the assumption of additional motion full compensation and it consists of autonomous digital compensators and regulators settings determination. In order to examine the effectiveness of the proposed methods it has been conducted calculation and simulation of two-dimensional autonomous digital control system of extractive distillation process on the base of the known and proposed approaches. The analysis of the results obtained shows regulation improvement and autonomy maintenance in the system with corrective links ensuring low sensitivity to variations of the twodimensional object transfer functions parameters with the output values independent control. Keywords: multi-loop connection, non-stationarity, low sensitivity, autonomous digital control system, corrective links. Contacts: E-mail: kudryashovvs@mail.ru Pp. 01-11.
