用matlab 中的Simulik设计的PID程序，适用于压缩机！(The Simulik with matlab PID design procedure for the compressor!)

说明：  这是在网上下的一个东东，很有用的，现在拿来和大家共享,是《参数估计和逆问题》的matlab程序(This is the Internet under a Dongdong, very useful, and we used to share, "parameter estimates and the inverse problem" Matlab procedures)

1、编写M-文件Matlab函数，分析特定字符串中的单词数量和句子数量。 2、编写M-文件脚本，调用前面的M-文件函数，实现数据输入，结果输出。 3、编写GUI程序，调用步骤1中的Matlab函数，在界面上实现数据输入、结果输出。 (1, the preparation of the M-file Matlab functions, analysis of the number of words and sentences the number of a particular string. 2, the preparation of the M-file script, call the front of the M-file functions, data input, output. 3, to write a GUI program, Matlab function call in step 1, the data input interface, the resulting output.)

希望学习优化设计原理的同学能够好好利用这个资料啊(Want to learn the principles of optimal design students can take advantage of this information ah)

给出了fhss调制解调的程序代码，通过编程描述了fhss的信号谱、功率谱(Given fhss code modulation and demodulation, by programming the signal described fhss spectrum, power spectrum)
