摘要： 研究了含有参数不确定及外部扰动的带有TCSC(thyristor controlled series compensation)的单机无穷大母线系统的鲁棒控制问题.针对描述单机无穷大母线系统的非线性三阶模型,将自适应理论和L2增益干扰理论相结合,并用逆推法构造出系统的存储函数,设计出了系统的非线性自适应鲁棒控制器.所设计的控制器不仅能够保证系统状态有界,而且能够有效地抑制外部干扰对系统输出的影响.仿真结果表明,所设计的控制器能够在很短的时间内使系统恢复稳定的状态,说明其控制是有效的.

Abstract: The robust control problem was studied for the single machine-infinite bus containing thyristor controlled series compensation (TCSC) power system with parameter uncertainties and external disturbances. Based on a nonlinear third-order model for a single machine-infinite bus system, two kinds of nonlinear controller were designed using backstepping methods. With backstepping, the origin nonlinear system does not 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 revealed that the controller designed by backstepping possessed good performances.
