说明：  先进PID控制matlab仿真(第二版)源程序，作者：刘金琨，电子工业出版社，2004年9月第一次印刷。在控制方向十本不错的书，里面的控制算法很值得借鉴！(Matlab simulation of advanced PID control (second edition) source, Author: Liu Jinkun, Publishing House of Electronics Industry, in September 2004 the first printing. 10 in the control of the direction of a good book, which control algorithm is worth learning!)

基于PID控制，其仿真效果明显，能够达到预期的效果，希望以后能研究出更好的控制。(Based on PID control, the simulation results significantly, to achieve the desired results, I hope to be able to come up with better control.)

语音识别是近年来发展非常迅速的一项计算机智能技术，广泛应用在语音控制、身份识别等多个领域。本次项目主要研究语音识别的预处理过程和特征参数的提取环节。通过对原始语音信号进行预加重和分帧、加窗，滤除低频干扰，提升对语音识别有用的部分，消除了部分噪音和失真。预处理之后进行信号的特征提取，主要选取了短时平均过零率和MFCC两个特征参数，应用matlab软件绘制波形图并提取特征参数矩阵，为之后的语音信号的识别打下了基础。(Speech recognition is a computer intelligent technology which has developed rapidly in recent years. It is widely used in speech control, identity recognition and other fields. This project mainly studies the pretreatment of speech recognition and the extraction of feature parameters. Through pre-emphasis, framing and windowing of the original speech signal, the low frequency interference is filtered out, the useful part of speech recognition is enhanced, and some noise and distortion are eliminated. After pretreatment, feature extraction of signal is carried out. Two feature parameters, short-term average zero-crossing rate and MFCC, are selected. Waveform diagram is drawn by MATLAB software and feature parameter matrix is extracted, which lays a foundation for speech signal recognition.)
