本程序可以较好的实现模糊PID控制的功能，给大家提供一种参考。(it s good for fuzzy-PID controler system.)

本程序，包含QPSK，OQPSK的产生过程，I、Q领路信号抽取，他们的频谱，包络情况，经过带通滤波器后的变化，经过非线性放大器后的频谱变化等。是一个很好的学习例程！(This procedure, including QPSK, OQPSK production process, I, Q signal extraction lead the way, their spectrum envelope case, after band-pass filter after the change, through non-linear changes in the spectrum after the amplifier. Is a good learning routines!)

维特比译码仿真程序 cnv_encd.m　卷积编码程序 viterbi.m　　卷积译码程序 其它的是viterbi.m中用到的子函数(Viterbi convolutional coding cnv_encd.m simulation program procedures viterbi.m other convolutional decoding procedure is used in viterbi.m Functions)

This simulation is done on basis to calculate the electricity cost for required time of usage

使用SRUKF（平方呢无迹卡尔曼滤波算法）进行双星编队的轨道状态的估计，并且分析了不同编队构形的可观测性(square-root unscented kalman filter was designed to accomplish the optimal estimation of double satellite. )

迭代自组织数据分析，有较好的参考价值，采用了小波去噪的思想。( Iterative self-organizing data analysis, There are good reference value, Using wavelet denoising thought.)

基于VSC-HVDC的多端柔性直流输电系统小信号模型及解耦控制 (The flexible multiterminal HVDC system based on VSC- HVDC small signal model and the decoupling control)

本代码设计的切比雪夫1型滤波器，与MATLAB中的切比雪夫滤波器不同的是输出为未归一化的零极点，输入只要是通带频率，通带波动，截止频率，阻带衰减即可，更便于抄做(The code design of Chebyshev Type 1 filter, and MATLAB in the Chebyshev filter output is not different is that the poles and zeros of the normalized input as long as the pass-band frequency, pass-band fluctuations, cutoff frequency, stopband attenuation can be more easily copied to do)

说明：  龙格库塔算法的两个MATLAB程序，供大家借鉴。(Runge-Kutta algorithm two MATLAB programs for everybody' s reference.)
