An adaptive backstepping control to ensure the stability and robustness for boost power converter in DC microgrids

چکیده
In recent years, the power electronic load infiltrates into microgrid in form of constant power, and its negative impedance characteristics threaten stability system. To alleviate instability caused by loads (CPLs) (CILs) boost converter DC microgrid, an adaptive backstepping control (BSC) method is designed. Firstly, based on dynamic model converter, input voltage estimator designed, which introduced to improve robustness change voltage. addition, anti-interference performance system ensure static error free tracking output voltage, extended nonlinear disturbance observer (ENDO) used compensate for influence mismatched uncertainty, optimized BSC uses fewer initial parameters operation. Finally, large-signal proposed verified using Lyapunov theory, ensures global trajectory reference fast control. Through MATLAB simulation hardware loop experiment (HIL), compared with BSC+NDO verify effectiveness superiority algorithm.
