采用偏最小二乘法，到达过程是的泊松过程，结合PCA的尺度不变特征变换(SIFT)算法，感应双馈发电机系统的仿真，匹配追踪和正交匹配追踪，进行逐步线性回归，是学习PCA特征提取的很好的学习资料。

- Partial least squares method, Arrival process is a Poisson process, Combined with PCA scale invariant feature transform (SIFT) algorithm, Simulation of doubly fed induction generator system, Matching Pursuit and orthogonal matching pursuit, Stepwise linear regression, Is a good learning materials to learn PCA feature extraction.
