Abstract

Adopting MPC to a fast changing system has always been a challenging problem due to the computational efficiency. As the equivalent aggregation strategy and the fast algorithm based on MPC proposed, the computational efficiency has been promoted greatly. This paper improves the fast algorithm combined with the equivalent aggregation strategy, and investigates the feasibility of adopting the fast algorithm based on MPC to DC-AC power inverter system which switching time is 52 μs. Simulation and the experiment have verified that the fast online MPC algorithm applied on the fast sampling system with embedded platform implementation works well.
