The Design of Nonlinear H_ ∞ Robust Controller for Thyristor Controlled Series Compensator

为充分发挥可控串补电容装置的作用 ,提高电力系统暂态稳定性 ,基于状态反馈线性化方法和线性H∞ 控制理论介绍了一种非线性H∞ 鲁棒控制器的设计方法 ,这种设计方法对原非线性系统具有鲁棒最优性。同时依据该方法设计了电力系统TCSC的非线性H∞ 鲁棒控制器 。

In order to improve power system transient stability and bring the thyristor controlled series compensator into full play, a design method for nonlinear H ∞ robust controller is introduced, which is based on the combination of the linearization approach of feed back state and linear H ∞ control theory. It is of robust optimization for nonlinear system. A nonlinear H ∞ robust controller for TCSC is obtained by this method. Its disturbance attenuation performance and practicality is discussed.
