Abstract

PURPOSE:To decrease the integral quantity of an overshoot component, etc. which is caused when the load changes suddenly and to shorten the time of adjustment, by selecting the output of a control part by a specific method and in accordance with the differential quantity of the deviation between the target value and a process variable signal. CONSTITUTION:The arithmetic processes 2-4 of proportion, integration and differentation are applied to the deviation TER of the target value TUP and the process variable signal TWO. This result of arithmetic is deivered to control a process 7. In this case, the output TC of the control part is fixed at a limiting value TCmax or TCmin corresponding to the plus or minus of the differential quantity VTD at a time point ts when the quantity VTD, the result of the arithmetic, exceeds the 1st set value VS1 and then the target value TUP has no change. Then the fixture to the limiting value of the output TC is released at a time point tE when the quantity VTD crosses the 2nd set value VS2 corresponding to the plus and minus of the quantity VTD. And a selecting part 8 is actuated to carry out the PID control.
