《工程控製論(英文版)》: On—off servomechanisms have the great advantage that comparatively simple systems of this kind can be made to handle large amounts of power.This is often difficult to achieve with servomechanisms of other types.On the other hand, on—off servomechanisms are definitely nonlinear systems, and, as will be shown in Chap.10, their performances tend to be inferior to those of the systems we have considered previously.Briefly, an oscillating control servomechanism is a modification of an on—off servomechanism, which enables us to secure the advantage of linearity without sacrificing the advantage of large power—carrying capacity. Before proceeding to the treatment of oscillating control servomechanisms proper, we shall present a general theoretical result, upon which the theory of all such systems is based.Let us consider a device having the following property: According as the input signal x(t) is positive or negative, the output signal y(t) is + A or —A, where A is a fixed constant.We may think of such a device as an ideal relay, an on—off system with zero threshold.Suppose that the input signal to the relay is x(t)=E0sinωt + kE0 sin ωt (6.8) where E0, k, ω0 and ω are constants.In connection with oscillating control servomechanisms, the term E0 sin ω0t will be a persistent oscillation in the system, and kE0 sin ωt will be an applied signal or modulating signal.We shall calculate the corresponding output y(t) presently. ……
