Abstract
PURPOSE: To enable dealing with slow disturbance and gentle change of process constant by changing the limit value or regulator output using an average value of the regulator output in a proper period of time.
CONSTITUTION: The shifting tendency of the central value of control operational output MV of a regulator is calculated from an verage value of the control operational output in a fixed period from present retrospectively to the past using the first average operator, the center setting device and the second subtracter. Then, basing on the above, the upper limit value and lower limit value of a signal limiting device is changed without changing the width of limit. Since a stopper 3 that regulates the discharge from the first tank is controlled by such output of the signal limiting device, the level of the second tank 5 can be maintained within an allowable limit even against slow disturbance and gentle change of the process contant.
