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 frame 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).
