本文研究了当给定的频率响应数据不一定位于均匀间隔的频率网格上时的“∞系统辨识”问题。本文导出了一大类鲁棒收敛的辨识算法。一个特定的算法进一步检查和明确的最坏情况下的误差界（在∞范数）推导出离散时间和连续时间系统。最后通过一个实例说明了算法的应用。
In this paper, the problem of ‘system identification in ℋ∞’ is investigated in the case when the given frequency response data are not necessarily on a uniformly spaced grid of frequencies. A large class of robustly convergent identification algorithms is derived. A particular algorithm is further examined and explicit worst case error bounds (in the ℋ∞ norm) are derived for both discrete-time and continuous-time systems. An example is provided to illustrate the application of the algorithms.
