摘要
为了提高晶闸管串联补偿装置(thyristor controlled series compensation,TCSC)控制器对系统的鲁棒性和反应速度,设计了一个极点约束下的多目标控制器。利用线性矩阵不等式(linear matrix inequalities,LMI)进行H∞控制研究,在理论和设计上都有很多优点,得到输出反馈H∞控制器,提高了系统的鲁棒性。仿真结果也表明设计的TCSC控制器可以保证系统的暂态稳定性。
In order to improve system robustness and response speed, a multi-objective thyristor controlled series compensation （TCSC） controller under pole region constraints is designed. The linear matrix inequality （LMI） technique provides a new approach to H∞ control for many virtues in theory and design. Then the output feedbacks of H∞ controller can increase system robustness. Simulation results also show that this controller can assure system transient stability.
