摘要
Boost converters are widely used in several applications such as solar PV systems, energy storage systems, etc. In order to improve its dynamic performance, several model predictive control (MPC) strategies have been proposed to govern this DC-DC converter. However, in general, they require long prediction horizons to achieve a stable closed-loop due to its well-known non-minimum phase behavior. A simple but effective MPC strategy for DC-DC boost converters is proposed in this work. The advantage of this proposal is that it requires only one-step prediction horizon to govern the converter. Moreover, the proposed controller belongs to the continuous control set MPC (CCS-MPC) family, which provides a constant switching frequency.
