Measuring device including feedback control system and feedback control system

摘要

PROBLEM TO BE SOLVED: To provide a feedback control system capable of converging a feedback value to a target value without setting a large loop gain. A feedback control system that inputs a target value and outputs a control value, outputs a gain element, a feedback element for inputting a control value, and outputs a difference between a target value and an output of the feedback element. It includes a subtraction unit to be input to the gain element, and an addition unit to add the output of the gain element and its own output and output it as a control value.
