先进PID控制及MATLAB仿真。。。书籍光盘内容。很火的一本书(Advanced PID control and MATLAB simulation. . . Books CD-ROM content. It fires a book)

matlab程序源码，可以在图像中隐藏信息(Hiding data in an image)

constructive role of noise in signal detection from parallel arrays of quantizers.(A noisy input signal is observed by means of a parallel array of one-bit threshold quantizers,in which all the quantizer outputs are added to produce the array output.s(t)=s1(t)with prior probability P0,or s(t)=s0(t)with prior probability P1=1-P0 input signal-noise mixture x(t)=s(t)+n(t) x(t) is observed by means of a parallel array of M threshold comparators. yi(t)=U[x(t)+wi(t)-theta],i=1,2...M.wi(t) is threshold noise.Y(t)=y1(t)+y2(t)+...yM(t), the array output Y(t) is meansured at T distinct times.the plot is fthe theoretical value of minimal detection error probability Per varied with sigma.)

说明：  通过状态空间方法建立了线性二自由度的车辆模型，然后通过转换，将状态空间转换成传递函数的形式，能看到速度变化后，质心侧偏角和横摆角速度的变化趋势。(The vehicle model with linear two degrees of freedom is established by the state space method, and then the state space is transformed into the form of transfer function through transformation. After the speed changes, the change trend of the sideslip angle and the yaw rate of the center of mass can be seen.)

本书采用pdf格式，内容新颖，题材丰富，是初学matlab的最佳选择。(This book uses pdf format, content, novel, rich in subject matter is matlab beginners the best choice.)
