| 摘要: |
| 利用Pade近似方法将时滞环节转化为状态空间形式，从而建立考虑传输时滞的开环电力系统线性化模型；采用基于H∞阻尼控制的混合灵敏度方法对所建模型进行鲁棒控制器设计。时域仿真结果表明：所设计的鲁棒控制器对电力系统广域时滞具有一定的耐受能力，同时可以抑制系统干扰的影响。 |

| Abstract: |
| The Pade approximation method is used to transform the time delay into the state space form, so as to establish the linearization model of the open loop power system considering the transmission delay. A robust controller using mixed sensitivity method based on H∞ damping control theory is designed for the model. Time domain si mulative results show that the designed robust controller has certain tolerant ability of the delay, and can also restrain the influence of interference. |
