Abstract
This work deals with the design and analysis of a
controller for a shunt active power filter. The design is based
on combined feedforward and feedback actions, the last using
repetitive control, and aims at the obtention of a good closedloop
performance in spite of the possible frequency variations
that may occur in the electrical network. As these changes
affect the performance of the controller, the proposal includes
a compensation technique consisting of an adaptive change of
the digital controller’s sampling time according to the network
frequency variation. However, this implies structural changes in
the closed-loop system that may destabilize the overall system.
Hence, this article is also concerned with closed-loop stability of
the resulting system, which is analyzed using a robust control
approach through the small gain theorem. Experimental results
that indicate good performance of the closed-loop system are
provided.
