An Advanced Adaptive Backstepping Control Method for STATCOM
An innovative approach to high robustness and anti-interference performance for static synchronous compensator(STATCOM)control systems is proposed to address the problems including parameter uncertainties and external disturbances which often deteriorate system performance significantly.Improvement is made in three aspects.Firstly,the adaptive backstepping control has been adopted to design the state-feedback control law and improve the transient stability of the STATCOM recursively.Secondly,In order to reduce high degree of coupling between the states and the estimation error,the adaptive law and the state-feedback control law are designed separately by using the immersion and invariance adaptive(I&I adaptive)control.Thirdly,the dissipation inequality is constructed between energy storage function and an energy supply function in each step.This can get a certificate theoretically that the energy is dissipated and the robustness of the control system.Moreover,the compared simulations show that more rapid speed response and stronger robustness can be obtained by the proposed approach than other advanced algorithms under the same conditions.
