摘　　要：针对含有静止无功补偿器(SVC)的单机系统中的各种不确定性因素,讨论了SVC的自适应鲁棒控制问题。将L2增益设计方法与Backstepping方法相结合,同时引入参数估计思想,通过递归地构造整个系统的能量存储函数获得闭环反馈控制律,保证系统对干扰输入具有L2性能,对未知参数具有自适应性。仿真结果表明,所设计控制器在系统受扰时可以使系统较快稳定,暂态过程中有效维持SVC接入点电压,系统对外部干扰具有较强的鲁棒性。Aiming at all uncertain factors of stand-alone system with SVC, adaptive robust control for SVC iS studied. With L2 gain design, Backstepping method and parameter estimation, closed loop feedback control law is gained in the course of constructing storage function recursively, which makes the system have L2 performance to disturbances input, and is self-adaptive to tmknown parameter. SimulatiOn results show that the controller can stabilize the system when disturbance occurs and maintain the SVC joint voltage effectively with good robustness.
