Abstract

PURPOSE:To perform stable control by sampling the process quantity at intervals of a time resulting from addition of the time constant and the dead time of a controller system and successively correcting the control output by the deviation between respective sampling measured values and the set value. CONSTITUTION:The preceding value and preceding values before this value of the sampling measured value a denoted as PVn-1, PVn-2-, and an adding element 31 operates the deviation between the sampling measured value and the set value, and an integration element 2 integrates the deviation from the adding element 31 to output K1SIGMA(SV-PVn-1)(j=1-infinity ). As the result, an output MV=KpSP+K1SIGMA(SV-PVn-1)(j=1-infinity ) is obtained from an adding element 32, and control is performed based on this output. This operation is successively repeated to not only correct the deviation between the measured value and the set value but also perform stable control while compensating a delay component.
