| 中文摘要 |
| 在多率采样系统中, 采样间隔不均匀. 本文综述了文献中有关多率采样系统的数学模型, 如线性周期时变模型、频域模型和连续状态空间模型等. 同时对相应的辨识方法, 如提升、频域方法、子空间辨识方法等, 也进行了全面的综述. 对多率采样系统辨识中存在的一些问题, 包括辨识模型的选择、一致性问题、带约束条件的辨识方法和辨识收敛性等, 也作了深入的讨论. |
| 英文摘要 |
| In multirate sampled systems, sampling periods are not uniform. This article briefly reviews the existing mathematical models of multirate sampled systems including the linear periodic time-varying model, the frequency domain model, and the continuous time state space model. The corresponding identification methods, such as lifting method, frequency domain method and subspace method, are also discussed. Model selection, consistency, constrained identification, convergence and other problems in the identification of multirate sampled system are deeply discussed. |
