Title:
FEEDBACK CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3283723
Kind Code:
B2
Abstract:
PURPOSE: To provide a closed loop feedback system having a open loop gain characteristic which is not changed even by the operating point of a system or the fluctuation of an environmental condition, or which is changed so as to be predictable.
CONSTITUTION: This is a closed loop feedback system constituted of first and second gain elements. A first gain element 104 has transfer function, Xd= Kg*(Xcont)2. Here, Xcont indicates the control change input signal of the first gain element, Xd indicates the change output signal to be controlled of the first gain element, and Kg and (z) are independent of Xcont. A second gain element 102 has transfer function, Xcont=h1(Xe). Here, Xe indicates the control change input signal of the second gain element, and Xcont indicates the change output signal to be controlled of the second gain element. The transfer function h1 is expressed as [1/h1(Xe)]* [δh1(Xe)/Xe]=Ke, and Ke is independent of Xe.
