| 摘要: |
| 本文给出了大规模控制系统的一种新的综合 LQG/H∞模型降阶方法。该方法同时兼顾了系统的时域特性与频域特性，使得对于在状态空间形式下的大系统的降阶既尽量保持原系统的频率特性，又具有与原对象更为接近的最小二次误差。 |

| Abstract: |
| A new LQG/H∞ model reduction method for large scale systems is given in this paper. Properties in both time domain and frequency domain are considered，hence the reduction in statespace form has advantages in keeping the frequency stability and it has a less LQG error. |
