极大似然估计法用于系统模型辨识，需要构造一个以观测数据和未知参数为自变量的似然函数。(Maximum likelihood estimation method for system model identification, the need to construct a likelihood function as independent variables to the observed data and the unknown parameters.)

风力发电控制器matlab仿真代码，大家一起参考学习。(Wind power controller matlab simulation code, with everyone learning.)

说明：  此模型中的撬棍不是使用IGBT或理想开关制造的。 通过 改变转子侧变流器的参考电压来模拟撬棍电路的切入和切出 。 该模型是使用MATLAB R2010a创建的。 控制策略是最常见的去耦 算法和MPPT(The crowbar in this model is not manufactured using IGBTs or ideal switches. by The reference voltage of the rotor-side converter is changed to simulate the cut-in and cut-out of the crowbar circuit. The model was created using MATLAB R2010a. Control strategy is the most common decoupling Algorithm and MPPT)

用matlab 编写的求解各类数值问题的代码，附有实验报告(code for various of numerical analysis )

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.
