PURPOSE:To control a process using a model in which an arbitrary part of a fluctuated range of a process variable is emphasized, by revising the model in a prescribed time interval. CONSTITUTION:A generator 6 is driven with a steam turbine 5. Sample values of a generating output G and a main steam flow rate S at a sample time (k) are taken as Gk and Sk respectively. Further, an error function is obtained by denoting the weight coefficient of the sample as omegak. When the generating output Gk is measured at the sample time (k), omegak is determined as omegak=h(Gk). When the omegak is determined from the weight function, the model not taking emphasis only on the vicinity of an operating level Gop of the generating output G is obtained. |
