H∞ damping control of power system with time delay
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.
