  • Feedback Control In General (AREA)

Abstract

PURPOSE: To exercise rational control with excessive control prevented by providing a feedback loop including an integral element and that including no integral element, by detecting the feedback loop, which does not include the integral loop, getting saturated, and then by controlling the integral element of the other loop by the detection output.
CONSTITUTION: Control element 1 including integral operation part 21 is connected to control element 101 which does not include the integral operation part and a controlled variable from controlled system 3 is detected by detectors 4 and 104 and then fed back to element 1 supplied with reference value Ref and element 101 using the output of element 1 as its reference value, thereby constituting the 1st and 2nd feedback control loops. The saturation of this element 101 is detected by level detector 20, the output of which operates electronic switch 22 to stop integral operation part 21 of the 1st feedback loop from operating. Consequently, excessive control is prevented and when the saturation is released, the integral operation is restarted for rational control.
