应用现代系统辨识理论,采用ARMAX的模型结构,利用预报误差法,辨识出在某一工况点附近工作的柔性风力机系统的功能模型,将辨识模型仿真结果与系统实验测量数据相对比,并对不同数据段多次辨识,以检验系统辨识模型的可靠性,从而给出一种新的风机系统建模方法,最后将新方法与传统方法进行对比。
Using the modern system identification theory and the model structure of ARMAX, the functional model of a flexible wind turbine system operating near a certain operating point is identified by using the forecast error method. The simulation results of the identification model are compared with those of the system experimental measurement data. Multiple identification of different data segments to verify the reliability of the system identification model to give a new modeling method of fan system, and finally the new method is compared with the traditional method.
