ABSTRACT:
An automatic control system controls a controlled variable serving as an object 2 to be controlled so that the object 2 approaches a predetermined target value, by means of an optimum regulator 4. The automatic control system include: a gain setting section 48 for setting a gain; a comparing section 48 for comparing the target value with the controlled variable serving as the object; and a weight control section 50 for weighting the gain set by the gain setting section so as to increase the weight from 0 to 1 within a predetermined period of time and for deriving a corrected manipulated variable in response to the time when a difference between the target value and the controlled variable comes within a range of a predetermined percentage of the target value, so that the corrected manipulated variable is added to the manipulated variable derived by the optimum regulator. Thus, the gain is controlled so as to gradually increase only within a restricted range, so that it is possible to quickly and accurately control an object.
