“…Authors in [18] have presented a backstepping DClink control, that achieves fast transient response but THD of the source currents are higher. On the other hand, various voltage and current estimation methods such as MCCF [21], reduced order generalized integrator (ROGI) [17], [23], comb filter based SOGI (CF-SOGI) [25] and FIR [22] have been addressed in the previous studies. From the quasi-real time results, the proposed control strategy including ST-SMC DClink control and voltage-current signal estimation with LKF exhibit superior performance with respect to current harmonics mitigation and convergence speed improvement.…”
