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。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 sinmlative results show that the designed robust controller has certain tolerant ability of the delay,and can also restrain the influence of interference.
