FIELD: continuous automatic control of process variables, such as temperature, pressure, flowrate, etc! for equipment possessing transport lag in power engineering, metallurgy, and other industries. SUBSTANCE: control-unit settings of device vary depending on intensity and direction of variation in both controlled variable and setting value due to introduction of dynamic units 9-11, module allocation units 12, 14, threshold elements 15, 16, logic unit 17 acting on control unit 6 and varying its settings. Units 9, 10, 11 determine character of variation of signal arriving from sensor 3, setting element 4, and adder 5. EFFECT: improved reliability of control. 4 dwg |
