This paper proposes an effective control scheme

for three-phase three-wire (3P3W) active power filter using

neural-based harmonic identification scheme. To achieve

excellent steady state and dynamic response, the feedback

control plus feed-forward control structures is utilized in the

proposed control algorithms. The steady-state error minimization

is achieved by the feedback loop, where the proportional

integral regulators were adopted in d-axis and

q-axis of the synchronous rotating reference fr a me synchronized

with grid voltages by using the phase-locked loop. The

adaptive linear combiners are utilized in the feed-forward

loop, which serves the purpose of load disturbance rejection,

and it significantly enhances dynamic performance of active

power filter (APF).
