希尔伯特黄变换,包括EMD分解，寻找极值和画图。(hilbert-huang transformation)

Several modal identification techniques have been developed in the past few decades, and their use is rapidly expanding due to new focus on the instrumentation of major structures. This paper focuses on the expansion of the eigenvalue realization algorithm (ERA)–observer Kalman filter identification
