Cloud Computing-Oriented Predictive Control for DC-DC Buck Converters

Cloud computing can greatly improve the efficiency of power converters in renewable energy systems, this paper proposes a cloud computing-oriented control strategy. To realize cloud control for buck converters, a cloud-based structure is presented, which eliminates the need for a local controller. Further, a networked predictive control method is proposed for such architecture to actively compensate for the time delays caused by the communication network. The stability of the control scheme can be derived via the closed-loop system. Finally, the effectiveness of the cloud control methodology is verified by experiments in a prototype system.
