NIE Yonghui, ZHANG Yichuan, MA Yanchao, et al. H∞ damping control of power system with time delay[J]. 2018, 38(10): 96-100. DOI: 10.16081/j.issn.1006-6047.2018.10.015.
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 simulative results show that the designed robust controller has certain tolerant ability of the delay
and can also restrain the influence of interference.
