Abstract
PURPOSE: To provide the subject device wherein variation components estimated by an estimating device are added to the actual value to produce an estimated value, whereby even when an estimator of relatively poor precision is used, the estimation precision can be improved.
CONSTITUTION: A signal 1b generated from an outer power source 1 applied to a control object 2 and a detecting signal 4a of the contol object 2 are added to an estimator 3, thereby to estimate a future state quantity of the control object 2. The estimated state quantity 3a is applied to an adder 6 by way of a waste time element 5 and a symbol converter 7, whereas it is applied directly to another adder. Accordingly, the output of the adder 6 represents the quantity of variation of the estimated value. The output of the adder 6 and the detection output 4b of the control object 2 are added by an adder 8, and its output is used as an estimated value of the control object 2.
