| 中文摘要 |
| 基于小波多分辨分析理论并结合面向控制的辨识思想, 提出一种多率采样系统分频段加权辨识方法. 首先研究了采样信息的一致性重构问题, 然后给出一种新颖的分频段加权辨识方法. 此方法的最大特点是对噪声不敏感, 易实现对感兴趣频段的精确建模, 便于和控制系统设计相配合. 仿真结果验证了这种方法的可行性. |
| 英文摘要 |
| Based on wavelet multiresolution analysis theory, this paper proposes a novel method for multirate sampled-data systems identification. First, the problem of multirate sampled_data reconstruction is studied, then a weighted band_wise identification method is presented. This method has the advantages of insensitivity to noise and convenience in modeling the interesting band of plant precisely, and easy incorporation with system design. Simulating results are given to illustrate that this method is feasible in model identification. |
