本文简述了八达岭风轮机系统及其数据采集的某些方法.用卡尔曼滤波算法估计了这个系统的参数,借助参数估计方法研究了其气动参数.为了找出这些信号的统计特性,使用了7T08S 信号处理器,得到了频谱图.本文用三种卡尔曼算法估计了模型的某些参数,并比较了这三种算法的计算机程序和运行时间. In this paper, some methods of data collection of the Badaling wind turbine system are briefly described, and the parameters of this system are estimated by Kalman filter algorithm and its aerodynamic parameters are studied by means of parameter estimation method. To find out the statistical characteristics of these signals, 7T08S signal processor, obtained the spectrogram.This paper uses the three kinds of Kalman algorithm to estimate some parameters of the model, and compares the computer programs and running time of these three algorithms.
