Abstract

PURPOSE:To avoid such a case where a prescribed range where no arithmetic operation is applied to the integration terms is set in response to the system characteristics, by inhibiting the integration arithmetic until the prescribed conditions are satisfied in case the set value of a PID parameter is decreased. CONSTITUTION:A PID controller 1 carries out the arithmetic operations of the proportion, integration and differentiation terms based on the prescribed PID arithmetic formulas by the arithmetic parts 4a-4c respectively. As a result, the deviation is eliminated between the measurement data corresponding to the working state of a controlled system 3 measured by a detector 2 and the value set previously by a setting a block 7. The sum total of these PID arithmetic results is multiplied by the prescribed proportion gain via a gain block 5 for calculation of an output rate to the controlled system 3. Then the normal PID arithmetic control is applied continuously until the prescribed start conditions (correction of set value into a lower level, etc.) are satisfied. Then it is decided under the fixed condition whether the integration arithmetic should be inhibited or not after said start conditions are satisfied.
