Four-leg inverters are used in critical applications
like UPS systems and satellite earth stations. Consequently,
generation of balanced voltages, with sinusoidal waveform, is
necessary for these inverters. Most papers dealing with 4-leg
inverters suggest classic controllers, such as PI controller, for the
system. However, the transient performance of the closed-loop
system does not become, accurately, adjustable and acceptable, in
some cases. This paper proposes Pole Placement control strategy,
via state feedback, for 4-leg voltage-source inverters to adjust the
transient performance of the closed-loop system. Simulation
results validate the theoretical results and proposed control
strategy.
