特徴とする制御システム。[Claims for Utility Model Registration] 1. A ratio setter that receives a set value signal and generates a set value ratio multiplication signal having a value obtained by multiplying the set value by a predetermined ratio smaller than 1; and the set value signal and the setting. a first changeover switch capable of receiving a value ratio multiplication signal, selecting a first state of selecting and outputting the set value ratio multiplication signal, and a second state of selecting and outputting the set value signal; a matching means for comparing the output of the first changeover switch and the actual measurement value signal to determine the deviation thereof; a control calculator that receives the deviation as an input; and a predetermined rise value that is larger than the output of the control calculator and the set value. a first state in which the rising value signal indicating the above is received, the rising value signal is selected and outputted; and a second state in which the output of the control calculator is selected and outputted.
a second changeover switch capable of switching to the first state when the actual measured value signal and the set value ratio multiplication signal are compared and the former is smaller than the latter; and when the former becomes larger than the latter, the first and second
A control system comprising: switch control means for bringing the switch into the second state. 2. In the control system according to claim 1, wherein the ratio is close to 1,
A control system characterized in that the first and second switches are switched when the actual measured value approaches the set value.
