| 摘 要： | 针对带有晶闸管控制串补(TCSC) 的单机无限总线系统, 利用浸入和不变思想设计了基于状态反馈的非线性阻尼控制器. 通过选定一个特定的二维目标系统和映射函数, 将所研究的对象浸入其中, 使得所设计的非线性阻尼控制器在不需要构造Lyapunov 函数的情况下即可保证闭环系统的渐近稳定性和轨迹的有界性. 仿真对比结果表明了采用所提出方法设计的控制器是有效的, 且能够明显提高闭环系统的暂态稳定性. |

| Abstract: | A nonlinear state-feedback controller design scheme based on immersion and invariance methodology is proposed for single machine infinite bus systems with thyristor-controlled series compensation. A nonlinear damping controller is obtained by choosing a stable target system and some designed mappings, which efficiently avoids choosing Lyapunov function and guarantees that all trajectories of the closed-loop system are asymptotically stable and bounded. Simulation result shows not only the validity of the proposed methodology but obviously enhances the transient stability of the closed-loop system. |
