摘要: 针对带有TCSC(ThyristorControlledSeriesCompensation)的单机无穷大总线系统的非线性二阶模型,使用逆推方法设计了TCSC的非线性控制器·基于逆推设计方法,无需对原系统进行线性化,并能保证闭环误差系统在Lyapunov意义下渐近稳定·当系统存在常参数不确定性,例如阻尼系数不能精确测量的情况下,应用自适应逆推方法还可以设计一个动态反馈控制器,其中含有对未知参数的实时估计·设计过程表明逆推方法设计的控制器拥有更优越的性能·

Abstract: Based on a nonlinear second-order model for a single-machine infinite-bus system with TCSC, two kinds of nonlinear controller were designed using backstepping methods. With backstepping, the origin nonlinear system doesn't need to be linearized and the closed-loop error system is guaranteed to be asymptotically stable. When damping coefficients is measured inaccurately, a dynamic feedback controller can be designed using adaptive backstepping containing the real-time estimation of uncertainty parameter. The design procedure reveals that the controller designed by backstepping possesses good performances.
