Abstract

PURPOSE:To suppress the overshoot, by starting the control only with the proportion and differentiation terms when the target value is changed and at the same time carrying out the control with addition of the integration term at the moment when a prescribed period of time elapses in case when the output deviation is less than a certain value of the changed target value or after the target value is changed. CONSTITUTION:The output deviation, i.e. the difference signal between the target value TUP and the process variable signal (output value) TWO of a process 6 is fed to each arithmetic part of proportion 2, integration 3 and differentiation 4 respectively. In this case, however, a selection part 7 is provided at the input side of an integral arithmetic process part 3. The part 7 fixes the output TERi at phi at the moment when a change of the target value is detected. Then TER= TERi is satisfied when the output deviation TER reaches x% of the changed degree of the target value. If the deviation TER does not reach the above-mentioned x% owing to the load conditions, etc., TER=TERi is obtained when a certain period of time elapses.
