TCSC的非线性逆推设计
Nonlinear Backstepping Design for TCSC
【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 secondorder model for a singlemachine infinitebus 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 closedloop 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 realtime estimation of uncertainty parameter. The design procedure reveals that the controller designed by backstepping possesses good performances.
