Abstract
In this work, a MPC strategy based on optimal switching sequences is proposed for 4-leg grid-tied converters. Extensive experimental tests presented here have demonstrated that the proposed control method achieves a good performance in both steadystate and transient conditions, even for reference currents having high harmonic content. The proposed OSS-MPC controller imposes the converter to operate with a fixed switching frequency and a predefined harmonic spectrum without compromising the inherent fast dynamic response of the predictive control strategies. In addition, users can tune the controller in a decoupled manner to establish different dynamic responses on the α, β, and γ components of the grid-currents. Therefore, the proposed controller is suitable for three-phase four-wire active-filter applications and distributed generation systems.
