摘　　要：传统的H∞控制理论在电力系统中的应用有种种限制,线性矩阵不等式 (LMI)技术为多目标控制器的综合提供了新的途径。借鉴有极点区域配置约束的混合H∞ /H2 问题的LMI解法,设计了多目标H∞电力系统稳定器用于阻尼低频振荡。特征根计算与仿真分析表明,该控制器可在较大范围运行条件情况下向系统提供足够的阻尼。Traditional H_∞ control theory has many limits in the application to power system. Linear Matrix Inequality (LMI) technique provides a new approach for the synthesis of multi-objective controller. Based on the LMI for mixed H_2/H_∞ design under pole region constraints, a multi-objective H_∞ power system stabilizer (PSS) for damped low-frequency oscillation is developed. The eigen value analysis and simulation show that the controller can provide enough dampings in many operating conditions.
