本文对门函数响应法所得出的杜氏变换与杜氏积分子以论证。在信号分析方面，通过杜氏变换引申出信号宽谱密度的新概念，并据此求出典型控制输入信号的杜氏变换对。

In this paper , the Du Transform and Du Integral are discussed in detail , and the Du Transform pairs for typical control inputs are expressed and their width spectra are plotted .

四，由于系统的典型输入为斜坡信号，不同于一般控制系统的阶跃信号，根据系统的性能指标，作者除了采用传统的PID控制算法之外，还采用了最小拍无波纹的设计方法。

Fourthly , because the system model input was the pitch signal , different from step signal of general control system , according to the system performance index , the author used the traditional PID control algorithm , but also has used the smallest racket non-ripple design method .
