针对带有TCSC(Thyristor Controlled Series Compensation)的单机无穷大总线系统的非线性二阶模型,使用自适应动态面方法设计了TCSC的非线性控制器.此设计方法,无须对原系统进行线性化,并能保证闭环误差系统渐进稳定,对于系统中的参数不确定性,具有较强的鲁棒性和自适应性.此控制器简单易于实现,其有效性通过仿真实例获得了验证.
Based on a nonlinear second-order model for a single-machine infinite-bus system with TCSC, nonlinear controller is designed by using adaptive dynamic surface method. The original nonlinear system needn' t to be linearized and the closed-loop error system is guaranteed to be asymptotically stable. The controller has good robustness and adaptability for the parameter uncertainty. It is easy to be realized. The effectiveness of the proposed control scheme is verified by simulation.
