采用信号包络和差分方式进行信号模式识别，通过变换产生时域解析信号SKH ，即信号的复包络，得到零中心归一化瞬时绝对值的标准偏差。 (Differential use of signal envelope and the way the signal pattern recognition, transformation generated by time domain analytic signal SKH, the signal complex envelope, zero-center normalized standard deviation of the instantaneous absolute value.)

学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)

近红外光谱提取后，matlab环境下可对NIR光谱数据进行正交信号校正(After the near-infrared spectrum extraction matlab environment can NIR spectral data orthogonal signal correction)

对灰度图像进行立体匹配，在图像的最大视差范围内进行搜索(To stereo matching of gray image, the image of the maximum parallax within the scope of the search)

使用MATLAB工具箱LMI求解线性矩阵不等式，使用WHILE循序求解最小值。(Using the MATLAB LMI toolbox for solving linear matrix inequalities, solving the minimum sequential use of WHILE.)

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。 (Themohu function is used in mainly control applications. PIDCalc performs one iteration of the PID algorithm. While the PID function works, main is just a dummy program showing a typical usage.)
