Abstract

PURPOSE:To make control following up the slow variation of process characteristics stably while responding to the variation of operation characteristics of a process immediately. CONSTITUTION:An adapation device A, after originating a test signal TS, estimates process characteristics. The result of characteristic estimation is coupled with a process variable CV as the index of process characteristics and the couple is stored in said device A. As for all stored measurement points, an adaptation curve having an index CV as a variable is found and then an applied signal VA which corresponds to the value of the index CV showing vairation in characteristics from a process P is fixed by the adaptation curve and supplied to a regulation part C to set the parameter of process control. A measurement point obtained corresponding to the arrival of a new process output variable PV and input variable MV is added and stored and when the number of them exceeds a prescribed value, old data is discarded in the order of storage to updata stored data.
