Jamil, M., Sharkh, S.M. and Abusara, M. A. (2011) Current regulation of three-phase grid connected voltage source inverter using robust digital repetitive control. International Review of Automatic Control, 4, (2), 211-219.
Most of renewable and conventional energy sources generate DC/AC power at inconvenient frequency. An inverter is typically used to integrate such distributed generation systems into the grid. There is a growing interest in developing appropriate control strategies to ensure that the current fed into the grid has a low total harmonic distortion. In this paper, a control scheme for a three-phase grid connected inverter is proposed. The scheme contains a traditional conventional tracking controller
with a dual loop feedback system, and a plug-in repetitive controller. The working principle of the controller, stability constraints and trade-off between the steady state error and the dynamics response of the system are analyzed. The results indicate that the proposed repetitive feedback control scheme improves the steady state error and total harmonic distortion of the output current by
compensating for the distortion caused by grid voltage harmonics.
