要求使用继电自整定方法对其实施自适应PID控制。
1、选择采样时间0.1s，把对象离散化。
2、加继电（开关）控制，测量对象的Tc,Kc。
3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。
4、实现闭环控制。
5、根据调节效果，修正PID参数。
(Require the use of relay tuning methods for its implementation of the adaptive PID control. 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)

比较两个不同的倒频谱分析方法cepstrum_computation
比较两个不同的倒频谱分析方法的一个有限的时间框架的言论,即基于fft算法的传统方法(与框架展开复杂的倒频谱),和一个分析方法基于求解有限阶分子多项式的根的倒频谱和直接计算多项式根的位置。(This MATLAB exercise compares two different methods of cepstrum analysis of a finite duration frame of speech, namely the conventional method based on FFTs (with frame unwrapping for the complex cepstrum), and an analytical method based on solving for the roots of a finite order numerator polynomial and directly computing the cepstrum the locations of the polynomial roots.)
