Summary: A System Identification Method for Nonuniform Sampling Data
Based on Missing Data Estimation
Shuichi Adachi, Member, Masayuki Tanji, Non-member (Utsunomiya University)
In this letter, a system identification method for nonuniform sampling data is proposed. First, nonuniform
sampling data is transformed to uniform sampling data whose sampling period is smaller than the original
data. Second, a system identification method with missing data estimation is applied to the transformed
data, since the transformed data contains a lot of missing data, Finally, the effectiveness of the proposed
method is examined though a numerical example.
