Abstract

PURPOSE: To reduce the work of operator and to improve the reliability of follow-up control by making the speed/load control signal of the variable valve, load limit signal or reactor maximum flow signal follow to the sum of pressure control signal and bias value constantly.
CONSTITUTION: A pressure control signal 10, speed/load control signal 11, load limit signal 17 and reactor maximum flow signal 18 are fed to the computer 21 which has automatic following function. By computing these with speed/load signal 22, load limit 23 and reactor maximum flow 24 bias values, a load set 25, load limit 26 and reactor maximum flow 27 modifications are provided as the outputs. With the speed/load limit signal 11, for example, the computer 21 decides whether the difference between both signals 10 and 11 is present as many as a specified bias 22, and modifies the load set memory 16 such that the value is made zero by means of pulse signals when the value is not zero.
