| 摘 要： | 研究了有色噪声扰动下闭环系统参数的无偏估计问题.基于偏差补偿最小二乘辨识方法,提出了一种用于闭环辨识的偏差补偿最小二乘法.这种方法不需要对噪声建模,即可获得闭环系统前向通道和反馈通道传递函数中参数的渐近无偏估计.

| Abstract: | This paper studies the problem of unbiasedly estimating the parameters of closed loop system in the presence of colored noises. A new bias-eliminating least-square method is proposed, which can achieve consistent estimates of transfer function in forward and feedback paths even without the noise models. |

| Keywords: | Consistent estimation least-square method closed-loop system. |
