某自行车商店的仓库管理人员采取一种简单的订货策略,现有如下五种订货策略，试以150天进行仿真测试，选择一个使总费用最小的订货策略.(Inventory problems )

实现不同模式之间可分性的分析，找到两类特征区别于彼此的特征点/段，以用于分类。(Separability between different modes to achieve the analysis)

基于Simulink的四旋翼飞行器动力学建模与简单PID控制.有相关文献。(Dynamic modeling and simple PID control of four rotor aircraft based on Simulink.)

说明：  matlab信号调制与解调方面的书 我自己看了一遍 感觉还不错(matlab signal modulation and demodulation aspects of the book I read it again I feel pretty good)

This is a GUI based system. The GUI is invoked from the command line by typing "ui_start". The GUI is self explanatory. Tool tips are given in blue color. The cursor needs to be positioned on these for detailed explanation. The main file is "runsim.m".It is recommended that 10000 runs (packets) be used for plotting frame error rates and 5000 runs for BER/SER. Obviously, you would require a fast machine!!! At least a P4 machine. We have used trace criterion for 4PSK states 4,8 and 16 as an example for 2x2 cases. The reader can use rank and determinant criteria, by commenting the trace criterion lines and copying the rank and determinant lines from the respective 2x1 cases. The SNR range can be varied by correcting the range at line 36 of file "runsim.m". This software has been tested with MATLAB version 6.0 and above with signal processing and communications toolbox options. (This is a GUI based system.

积分分离PID控制matlab M文件代码。 该控制里面将积分分离，在控制误差很小时才重新使用积分，这样可获得更好的控制效果。(Integral Separation PID control matlab M file code. The control inside the integral separation, re-use integral control error is very small when, so to get better control effect.)
