poincare-map-of-duffing--system

说明：  code of pendulum using pdi controller

利用matlab语言，设计带通滤波器，对声信号进行滤波处理，除去环境噪声。(Using matlab language, designed bandpass filter, the acoustic signal filtering to remove noise.)

用卡尔曼卡尔曼滤波跟踪平面质点的运动，首先建立一个平面坐标系，则这个质点的运动要三个变量来描述(Kalman Kalman filter to track the movement of the plane particle)

matlab 批量载入数据(matlab load data )

蛙跳算法,包含Flow_Shop_Scheduling_Problem、 Function_Optimization、 Knapsack_Problem、 Traveling_Salesman_Problem(flog leap algorithm, including Flow_Shop_Scheduling_Problem, Function_Optimization, Knapsack_Problem, Traveling_Salesman_Problem)

说明：  这个是交通流ＣＡ模型，能够较为真实的仿真出交通流的运行状况，对交通流元胞自动机的人可以学习学习(The CA model of traffic flow, to a more realistic simulation of the operational status of the traffic flow, traffic flow cellular automaton can learn to learn)

ofdm系统信道估计，基于LS,LMMSE,LRMMSE等准侧。是学习的好工具。(ofdm channel estimation system, based on LS, LMMSE, LRMMSE other potential side. Is a good tool for learning.)

用以进行睡眠信号的去趋势波动分析,可以分深睡段，浅睡段(DFA for sleeping data)

语音信号的基音检测与估计对信号的估计具有重要作用。用不同方法进行基音检测(Pitch detection signal and the estimated speech signal estimate plays an important role. Pitch detection using different methods)

说明：  运用matlab编写DNN程序，带有几个实例，有BP神经网络，relu，sigmod等~(Using matlab to write DNN program, with several examples, such as BP neural network, relu, sigmod, etc.~)
