matlab 基于PID控制器的BP神经网络系统的仿真(matlab PID controller based on BP neural network system simulation)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

说明：  可以实现一幅图像中彩色边缘的提取，实在matlab的条件下，有多种算子(Can achieve a color image edge extraction, it is matlab conditions, a variety of operator)

Matlab入门教材，可以作为入门是的读物。(Matlab entry materials, can be used as entry is reading.)

Matlab 图像检索源代码，灰度直方图方法，简单检索方法(Matlab image search)

用Rosen梯度投影法求解约束多维函数的极值 用外点罚函数法求解线性等式约束多维函数的极值 用外点罚函数法求解一般等式约束多维函数的极值 用内点罚函数法求解约束多维函数的极值 用混合罚函数法求解约束多维函数的极值 用混合罚函数加速法求解约束多维函数的极值 用乘子法求解约束多维函数的极值 用坐标轮换法求解约束多维函数的极值 用复合形法求解约束多维函数的极值 (Rosen gradient projection method for solving constrained multi-dimensional functions the extremal with outside point penalty function method for solving linear equality constraints multidimensional function the extremal with outside point penalty function method for solving the general extremum with of equality constraints multidimensional function within point penalty function method for solving constrained multidimensional function extremum with mixed penalty function method for solving constrained multidimensional function extremum with mixed penalty function acceleration method for solving constrained multidimensional function extremum multiplier method for solving constrained multidimensional function extremum with coordinate alternation method for solving constrained the multidimensional function extremum complex method for solving constrained multidimensional function extremum)

与前边的程序配套使用，模拟实现小波去噪。(And in front of the program to simulate the matching, wavelet denoising.)

FSK 信号的循环谱程序，验证了是正确的(The cycle of FSK signal spectrum procedure, verify the is correct)

变频器（频率自定义）+Dudt的LC滤波器（LC自定义）+电缆模型（长度自定义）+高频异步电机模型（参数自定义）(The LC filter inverter frequency (custom)+Dudt (LC) custom+ cable model (custom length)+ high frequency induction motor model (custom parameters))

说明：  FIR滤波器的设计，刚开始用matlab的可以参考下，(FIR filter example,those who just begin to learn matlab can refer to these programs.)
