| 中文摘要 |
| 本文讨论了单输入、单输出、离散、时不变因果系统的面向控制的Ｈ∞辨识问题，在该问题中，中心估计是最优的，插值估计是次优的，但一般都难以求取，本文提出了非插值类的代数算法，该算法计算量小，所得模型简单且估计出的Worst－Case误差较小，该算法是收敛的，因而具有较好的实用价值． |
| 英文摘要 |
| In this paper the robust control oriented Ｈ∞ system identification problem is studied.The system is supposed to belong to the class causal，shift-invariant systems.First，an algebraic algorithm based on algebraic approach is presented.Second，the characters of the algorithm is analysed.Finally，the worst-case identification error associated with the algorithm is evaluated and which shows the algorithm，s convergence.Since the algorithm can obtain a simple model by less computation and the worst-case error is small，it is of practical value. |
