linear_regression

用MATLAB实现加噪信号的消噪,用了三种常用方法。(de-noise programme by MATLAB，it is very useful for newerws.)

A very small 250-line library (written entirely in MATLAB) that allows multiple MATLAB programs to talk to each other, so that hundreds of processors can work together.

维纳滤波，能滤除干扰噪声，提取有用信号。但是当输入信号的统计特性偏离设计条件，它就不再是最佳的了，这在实际应用中受到了限制。 (Wiener filter, to filter out interference noise, extract the useful signal. However, when the statistical characteristics of the input signal deviates from the design conditions, it is no longer optimal, which has been limited in practical application.)

fuzzy 和PID的simulink仿真程序算法，实现了模糊控制和PID控制的仿真(fuzzy simulink simulation program and PID algorithm, fuzzy control and PID control simulation)

可以应用于动态卸载应力分析和能量分析，求解径向应力分析和应变。(It can be used to the analysis of the dynamic loading stress and energy .)

系统的结构参数和负荷情况都已给定时，调节可利用的控制变量(如发电机输出功率、可调变压器抽头等)来找到能满足所有运行约束条件的，并使系统的某一性能指标(如发电成本或网络损耗)达到最优值下的潮流分布。(Optimal power flow(OPF) is a fundamental tool in power system planning and operation.)

这是在上一个MIMO基础上再次集成了OFDM，包含了迫零算法、ldpc译码，以及OFDM的调制解调(This is on the basis of a re-integration of MIMO OFDM, it contains zero forcing algorithm, ldpc decoding, and OFDM modulation and demodulation)

说明：  先判断能控能观，再设计控制器，达到工程要求(controller design)
