abstract = "This paper provides a new design procedure for robust current
controllers applied to LCL-filtered grid-tied inverters suitable
for the integration of renewable energy sources. The design takes
into account the digital implementation delay, multiple resonant
controllers and operation under uncertain grid impedance. The
procedure is based on the optimization of an objective function
that allows to get a good trade-off between the settling of
transient responses and rejection of disturbances. A particle
swarm algorithm is used to find the optimal control gains and,
differently from other works, here the robust stability of the
closed-loop system under uncertain parameters is theoretically
certified by means of linear matrix inequalities. Experimental
results are shown, confirming that the closed-loop system with
gains obtained by the proposed procedure presents a good tradeoff
between robustness and performance, with suitable transients and
grid currents with low harmonic content, complying with
requirements from IEEE 1547 Standard, becoming a useful robust
control design alternative for power converters in the distributed
generation scenario.",
