Resumen:
A new structure of a PI current controller implemented in a synchronous d, q reference frame (SRF-PI), for grid-tied voltage inverters, is presented. The controller has a dead beat response for current reference tracking, reaching it in two samples. It also keeps the main feature of the SRF-PI controller: its ability to track without error a positive sequence current reference of fundamental frequency (in the absence of other disturbances). Furthermore, the controller ensures the full decoupling between the currents of axes d and q. The controller is compared, through simulation and experimental results, with one SRF-PI controller recently published in the literature. It is verified that the proposed controller introduces noticeable improvements in both the transient response and in the steady state response to perturbations in the control loop.
