ABSTRACT:
A closed-loop feedback system has first and second gain elements. The first gain element has a transfer function such that Xd=Kg * (Xcont).sup.z, where Xcont is a control variable input signal of the first gain element, Xd is a controlled variable output signal of the first gain element, and Kg and z are independent of Xcont. The second gain element has a transfer function h1 such that Xcont=h1(Xe) where Xe is a control variable input signal of the second gain element and Xcont is a controlled variable output signal of the second gain element. The function h1 is of a form which satisfies [1/h1(Xe)]*[.delta.h1(Xe)/.delta.Xe]=Ke, where Ke is independent of Xe.
