Application Research on Sliding Mode Control Algorithm Mixing Reaching Law to APF
Abstract：Although the active power filter （APF） is considered to be the most effective measure to cure the harmonic wave in the power grid now, but its control method inheres the problems of buffeting. Aiming at the practical requirements of APF on the performance of control, the algorithm with mixing reaching law is proposed based on the discrete sliding mode control. In the early stage of the sliding mode motion, the exponential reaching law is adopted, and in the later stage the variable rate reaching law is used. Thus, the buffeting of system would be weakened, the dynamic performance and tracking effect of system are improved.
