In this scheme, a reference modification
part is incorporated with the generally used synchronousframe
proportional-integral (PI) controller for the fast transient
response. Simulation and experimental results are presented and
show the effectiveness of the proposed current controller. In the
simulation and experimental results, both the current controller
and dc-link regulator show the conspicuous performance improvement.
It is also observed in the simulation and experiment
that the proposed current controller has a similar characteristic
as the synchronous-frame PI controller in the steady state and as
the minimum-time current controller in the transient state.
