fit_ML_normal - Maximum Likelihood fit of the normal distribution of i.i.d. samples!. Given the samples of a normal distribution, the PDF parameter is found fits data to the probability of the form: p(r) = sqrt(1/2/pi/sig^2)*exp(-((r-u)^2)/(2*sig^2)) with parameters: u,sig^2 format: result = fit_ML_normal( x,hAx ) input: x - vector, samples with normal distribution to be parameterized hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields sig^2,u - fitted parameters CRB_sig2,CRB_u - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

：根据内蒙古四子王旗某地2007年逐月平均风速袁选取设计风速为6m／s，根据某型号300 W交流永磁发电机的输出功率特性。利用Matlab编写的叶片优化设计程序，设计了300W水平轴风力发电机叶片。通过风轮与发电机的匹配，调整叶片参数，使之在小风时具有较高的风能利用系数，提高风力机的效率，在大风时具有较低的风能利用系数，从而达到大风时限速保护的目的。(: According to Inner Mongolia as a 2007 monthly average wind speed Yuan select the design wind speed to 6 m/s, according to a Model 300 W output power characteristics of permanent magnet alternator. Leaves written in Matlab to optimize the design process, design 300W horizontal axis wind turbine blades. The wind wheel generator matching adjust the blades parameter, so that has a high wind energy utilization coefficient of small wind, improve the efficiency of the wind turbine in high winds has a lower coefficient of wind energy utilization, so as to achieve high winds speed limit protection purposes.)
