pfatb_v1.1

该源码来自教程＜先进的pid控制及matlab仿真（第一版）＞，对初学者非常有帮助.(The source code from the tutorial <advanced pid control and matlab simulation (first edition)>, very helpful for beginners.)

This is a buck converter simulation. This simulation have the changing load in the changing time. This is a variable load simulation of buck converter.

该程序可以实现信号的分形计算，从而求解出所求信号的分形函数，在信号非线性研究中有很重要的作用。(The program can calculate the fractal signal, thus solving the request signals a fractal function, the study of nonlinear signal has a very important role.)

调用函数，并对函数进行求解，把数据存储，并画出其中几条图(Call the function, and the function is solved, the data is stored, and draw the diagram in which several)
