详细讲述了直接序列扩频差分锁相环的文章，包含具体的算法结构，并附有仿真结果。(A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential decoder and exactly one correlator, the proposed scheme avoids the problems of gain imbalance. The tracking error variance is derived by linear analysis. When the proposed DCDLL scheme is applied in ranging with additive white Gaussian noise (AWGN) channel, the performance of the proposed DCDLL scheme is about 1.4 dB better than that of one-correlator tau–dither loop (TDL), and near that of noncoherent DLL.)

三次B样条小波分解与重构算法程序，已经测试好了，可以直接使用的，提供给需要的朋友们(Three B-spline wavelet decomposition and reconstruction algorithm program has been tested OK, you can directly use, available to friends in need)

This is the bisection method for solving an equation f(x)=0

在这里，被控量是小车转角，向上回朔是舵机的转角，再向上就是用来控制舵机的PWM波的占空比，也就是说你的被控量是PWM波的占空比；一旦你的 舵机安装方式确定后，小车前轮的左右极限转角也就定死了，也就是说你的PWM波的占空比的变化范围也就确定了，即被控量的论域确定了，以我的为 例是1225到1725，显然S12的模糊机无法直接输出这么大的数值，在此对于输出量的隶属度函数我选用的是单值的，对应9个等级（0-8），即对应9个 PWM占空比值，即对应9个角度值。模糊语言等级、输出等级以及实际PWM占空比值的对应关系如下。 (www.hellodsp.com) 详细出处参考：http://www.hellodsp.com/bbs/viewthread.php?tid=688 )

牛顿法，一种高效的优化方法，对于无约束的优化问题有效(Newton, an efficient optimization method for unconstrained optimization problems effectively)

Data files are in Matlab format. Each file contains fan and drive end vibration data as well as motor rotational speed. For all files, the following item in the variable name indicates: DE - drive end accelerometer data FE - fan end accelerometer data BA - base accelerometer data time - time series data RPM- rpm during testing
