A new method based on extended adaptive backstepping for nonlinear control of TCSC
基于扩展自适应Backstepping设计的TCSC非线性控制的新方法

A new extended adaptive backstepping algorithm for general nonlinear systems in parametric feedback form is proposed.The method preserves useful nonlinearities and the real-time estimation of uncertainty parameter but does not follow the classical certainty-equivalence principle in the design of the parameter estimator and dynamics feedback controller.The proposed method can be applied to a single-machine infinite-bus system with thyristor controlled series compensation(TCSC).Finally,simulation results are given to demonstrate that the proposed method provides better system response and higher speed of adaptation than the design based on classical adaptive backstepping.
