分散保性能状态反馈励磁控制器

Excitation controller of decentralized guaranteed cost and state feedback

提出一种新型的电力系统鲁棒分散励磁控制方法,该方法基于LMI技术处理被控系统的参数不确定性。控制器采用线性反馈实现,其控制参数在有界范围内的变化能保证闭环系统的渐近稳定性。在IEEE3机9节点系统上进行的算例验证了分散保性能控制的有效性和鲁棒性。

A new strategy for decentralized guaranteed cost exciter control in power system was presented. The approach uses LMI technique to deal with the parametric uncertainty of the system controlled. It can be guaranteed the closed loop system asymptotic stability in a limitary parameter variation. The result in feedback control is linear and easy to be implemented. Tests on the IEEE9 bus system demonstrate the robust of the decentralized guaranteed cost exciter control for different disturbance and operation condition.
