摘要

提出了一种基于LMI极点约束分析的电力系统稳定器H2控制器设计方法。选择单机无限母线系统和Heffron-Phillips同步发电机数学模型，将所提控制器与传统PSS (CPSS)的有效性进行比较。H2鲁棒控制保证了系统在不同工况下的阻尼性能，鲁棒性优于CPSS。

Robust H2 power system stabilizer design using LMI techniques

This paper presents a H2 controller design approach for power system stabilizers (PSS) based on LMI pole constraints analysis for damping low frequency oscillations. A single machine infinite bus system and a Heffron-Phillips synchronous generator mathematical model are selected in order to compare the effectiveness of the proposed controller with conventional PSS (CPSS). The H2 robust control guarantees the damping performance for different operating conditions and its robustness is better than that of CPSS.
