Abstract:
Adaptive backstepping controller of cascaded static synchronous compensator (STATCOM) was proposed in this paper considering the nonlinear characteristic of cascaded STATCOM system. The controller obtained virtual control input of cascaded STATCOM by adopting the recursive idea of backstepping. It designed the system interim control rate according to the principle of certainty equivalence principle. Using the above system interim control rate, the design of voltage controller was completed and the Lyapunov equation of cascaded STATCOM system was set up. Using the Lyapunov asymptotic stability principle, the control inputs and adaptive rate of system parameters to ensure the stability of cascaded STATCOM were obtained. The correctness and effectiveness of adaptive backstepping controller was validated through experiments. © 2017, The editorial office of Transaction of China Electrotechnical Society.
