fit_ML_normal - Maximum Likelihood fit of the log-normal distribution of i.i.d. samples!. Given the samples of a log-normal distribution, the PDF parameter is found fits data to the probability of the form: p(x) = sqrt(1/(2*pi))/(s*x)*exp(- (log(x-m)^2)/(2*s^2)) with parameters: m,s format: result = fit_ML_log_normal( x,hAx ) input: x - vector, samples with log-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 m,s - fitted parameters CRB_m,CRB_s - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

Matlab simulation of PMSM with SPWM modulation. This is an example that use every single element of simulink library, so it can help you understand details of PMSM simulation. This simulation module was built by my own, any questions, pleases contact me.

非线性CSTH闭环控制程序，以CSTH为主(CSTH nonlinear closed-loop control，CSTH is important)

这个程序是一个风力机的三阶模型，采用桨距角控制，设计了转速的闭环控制系统(This program is the third-order model of a wind machine, using the pitch angle control, closed-loop control system design speed)
