Industrial Automatic Control Systems and Controllers Annotation << Back Un-exact Control of Process of a Vacuum Thermal Treatment Sokolov Yu.A. In this document a control system of a vacuum high-temperature furnace is considered. An algorithm of control by heat with using of a device of un-exact logic which is based on aqn experiment and an intuition of operator- thermist is described. A realization of this algorithm in view of a un-exact controller in a direct contour of control allow to exclude the operator and hand it functions to a un-exact control system. Key words: a vacuum thermal treatment of metals, a control system, an algorithm of control, an un-exact logic, a programmable controller. E-mail: sklvfi@inbox.ru. Pp. 11-14.
