| 中文摘要 |
| 本文研究了具有和非参数化不确定系统的集员辨识问题。分析表明利用我们在文[5]中提出的BEBL方法可以消除集员辨识中观测噪声引起的偏差。文中通过对系统输入数据的预滤波将已知零点嵌入系统，利用这些零点提供的信息将观测噪声引起的辨识偏差予以消除。 |
| 英文摘要 |
| The set-membership identification of systems with parametric and nonparametric uncertainty is studied in this paper. The bias induced by the additive noise is eliminated by using the Bias-Eliminated Least Squares Method proposed in [5]. A prefilter is connected to the input terminal of the system, so that some zero are inserted to the system. By using the information obtained from these known zeros the bisa induced by the additive noise is eliminated. |
