Abstract
- In this paper, a new structure of a proportional integral (PI) current controller implemented in a synchronous $d,q$ reference frame (SRF-PI), for grid-tied voltage inverters, is presented. The controller has deadbeat 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, in the absence of other disturbances, a positive sequence current reference of fundamental frequency. 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.
