Abstract: PURPOSE:To automatically tune a proportion (P) and integration (I) parameter at an optimum value by providing a set value fluctuation monitoring means for grasping the cause of the turbulence of a response waveform. CONSTITUTION:A set value fluctuation monitoring means 35 monitors whether a fluctuation quantity in the definite time of a set value SV exceeds a prescribed reference value or not, and when the fluctuation quantity exceeds a certain prescribed value, a flag 36 is set on.
