Optimal Three-vector Model Predictive Control for Grid-connected Inverter
Compared with the traditional d,q decoupling control method,the three-vector model predictive current control(3V-MPCC)of grid connect inverter has better steady state performance and faster dynamic response,but it has the disadvantage of large computational volume.For this reason,an optimal three-vector model predictive current con-trol(O3V-MPCC)algorithm is proposed based on desired sector selection.Firstly,the traditional 3V-MPCC is introduced and then the optimisation algorithm is proposed to make the predicted current as the desired current and the desired sector is quickly determined according to the principle of dead-beat control.Finally,an experimental platform with STM32F407VET6 as the core is built for verification.The results show that the proposed algorithm has good steady state and dynamic control performance,at the same time significantly reduces the execution time of the algorithm.
