Abstract
PURPOSE: To enable an accuracy water level control to be performed, by means of using the quantities capable of determinating the present water level by estimating the measured water level obtained only the relation of flowin quantity and flowout quantity as a predicting water level filter.
CONSTITUTION: For the purpose of controlling the water level such as a dum etc., the present water level is determined by means of predicting the water level of the dum, and of passing this by a predicting water level filter. Next, when the constants of the water level filter of next time are prepared, the preparation of the constants is effected as follows: The deviation of a flowin quantity and a flowout quantity is found at the counting time of a flow quantity, and next, a stored quantity per unit time is found. Next, the stored quantity of the dum at a prescribed time is found, thereby the water level of the dum is obtained. By this, the filter constant is determined, thereby the control of the water level can be performed with accuracy even when the water level change is generated.
