METHOD AND SYSTEM OF CONTROLLING PLANTS ABSTRACT OF THE DISCLOSURE In a method and system of controlling the operation of a plant by means of an electronic computer, the judg- ing conditions and control and supervisory operations corresponding thereto are described in tables from which a plurality of action lists having a standard form of plant state judging conditions plus controlling and supervisory operations are prepared. the contents of the action list are stored in the memory device of the computer. A process signal corresponding to a state of the plant is compared with a reference signal for produc- ing a trigger signal which is used to select a corres- ponding action list. The content of the selected action list is judged to produce a control signal for control- ling the plant. According to this invention it is possible to smooth- ly operate the plant at high efficiencies with an elec- tronic computer of simple and standard construction with- out the necessity of preparing block charts and flow charts requiring troublesome operations.
