摘　　要：针对带有TCSC的单机无穷大母线系统的三阶模型,在考虑阻尼系数未知的情况下,利用自适应动态面方法设计控制器,并获得自适应参数替换律.此设计方法由于加入了2个低通滤波器,既避免了传统的逆推算法对模型的不确定性反复多次求导,又避免了因"微分项的爆炸"引起的算法复杂性,从而简化了算法.所设计的鲁棒自适应动态面控制器保证了闭环系统的半全局渐进稳定并且使得输出跟踪所期望的轨迹.仿真研究结果表明了所设计的控制器的有效性和可行性.As strong nonlinear dynamic and large scale systems, the research of electric power system is very important. In this paper, based on the three-order models of single-machine infinite bus system with thyristor controlled series compensator（TCSC） and under the condition that system has unknown damping coefficient, a nonlinear adaptive robust controller and a parameter update law fire obtained using adaptive dynamic surface approach. The addition of filters allows the algorithms to be implemented without differentiating any uncertainty and dealing with the explosion of terms for adaptive backstepping. The controlled system is semi-global stable asymptotically for sufficiently fast filters. The simulation results demonstrate the feasibility and effectiveness of the controller designed by the method.
