中文摘要

      本文研究了带未建模动态系统的频域辨识问题，辨识结果为递推函数在单位圆上的有限个点估计及其误差界。理论分析和仿真结果都表明，本文采取的求取误差界的方法比文[4]的方法导致更佳的估计和较小的误差界。

英文摘要

      This paper investigates the problem of frequency-domain identification for systems with unmodelled dynamics. The resulting algorithm yields finite point eatimates of transfer function on the unit circle and their conresponding error bounds. It is shown by both theoretical analysis and simulation results that our approach in better eatimates and tighter error bounds than that adopted in [4].
