PI调节器参数的直流双闭环仿真程序，参数需要调节，网友学习交流matlab程序代码。(PI regulator parameters of DC double-loop simulation program, parameters need adjustment, users learn matlab program code.)

本人亲手做的一个matlab扩频通信系统simulink仿真系统。从发送端到接收到，每部分都相应得加了示波器或频谱仪，可以对照理论清楚观察到信号发生的变化。matlab6.5及以上版本上运行。(I personally make a matlab Spread Spectrum Communication System simulink simulation system. Send-ended to receive from every part of a corresponding increase in the oscilloscope or spectrum analyzer can be clearly observed in the control theory of signal changes. matlab6.5 and above to run.)

曲线拟合系统，输入阶数进行拟合计算和插值计算(Curve fitting system to fit the input order of calculation and interpolation)

it is used to plot cicul by nice way. Plot a circle v - center (either 2 or 3 dimensional vector) r - radius default = 1 c - color default = white n - number of plot points default = 20

基于模糊控制的PID温度控制器的设计 :将模糊控制和PID 控制相结合起来，通过模糊控制实现PID 参数自适应的方法来控制系统温度。这种Fuzzy- PID 策略，模糊控制的采用不是代替PID 控制，而是对传统控制方式的改进和扩展，它既保持了常规PID 控制系统结构简单、使用方便、鲁棒性强、控制精度高的优点，又采用模糊推理的方法实现了PID 参数PK、IK、DK的在线自整定，兼具了模糊控制灵活性、适应性强的特点，相比单纯的任一种控制效果都要好(PID temperature controller design based on fuzzy control: fuzzy control and PID control combine to achieve PID adaptive approach to control system temperature by means of fuzzy control. This Fuzzy- PID strategy is not to replace the use of fuzzy control PID control, but the traditional control methods to improve and expand, both to maintain a simple and conventional PID control system structure, easy to use, robust, and high control accuracy advantages, but also the use of fuzzy inference PID parameters to achieve the PK, IK, DK-line self-tuning, both the fuzzy control flexibility, adaptability features, compared to simply have a good control effect either)

用MATLAB编程实现巴特沃兹低通、带通滤波器(Using MATLAB programming巴特沃兹low-pass, band-pass filter)

说明：  输入一串字符，统计其中各种字符：大小写字母、数字、空格、其他字符的个数(input string of characters, statistics on various characters : uppercase and lowercase letters, numbers, spaces, a number of other characters)

说明：  一个matlab 的HOUGH变换程序，主要用于边远检测和图像处理。中间包含了CANNY算子等多种算法 还是很有用的(a Matlab HOUGH transform procedure, mainly for remote detection and image processing. Included among the Canny operator of a variety of algorithms or very useful)

说明：  fourier 变换与MATLAB实现 张德丰(fourier transform and MATLAB implementation Zhang Defeng)
