Abstract
In this paper two different update schemes for the recently developed
plug-in direct particle swarm repetitive controller (PDPSRC) are
investigated and compared. The proposed approach employs the particle
swarm optimizer (PSO) to solve in on-line mode a dynamic optimization
problem (DOP) related to the control task in the constant-amplitude
constant-frequency voltage-source inverter (CACF VSI) with an LC output
filter. The effectiveness of synchronous and asynchronous update rules,
both commonly used in static optimization problems (SOPs), is assessed and
compared in the case of PDPSRC. The performance of the controller, when
synthesized using each of the update schemes, is studied numerically.
