Abstract
PURPOSE: To prevent the overshoot at the starting time and to smoothen the change- over to normal operation, by means of clamping a control constant of a regulator at the starting time, and of changing over the output of the regulator and the output of a lump function generator.
CONSTITUTION: A set value Es and a measured value Ep are added to a regulator 1 which operates a proportional integration, and the output Eo1 is sent to a low value selection circuit 7. A time constant is settable on this circuit 7, and an output Eo2 of a lump function generator which can hole the output is also added, thereby the low one is sent to a control valve 11. The output Eo is returned to the regulator 1, thereby the lump is never generated even to the returning time from the starting time (the output Eo2 is selected). And, at starting time, the control constant is clamped by means of closing contacts 2, 3 by the output of an alarm 6, but it is returned to the constant of optimum control.
