Power electronic device is a hybrid system and this feature shall be considered in the design ofcontroller. FCS-MPC can connect the discrete signal and the continuous signal by the corresponding mod-el. Study of FCS-MPC control for power electronic device is the supplementary of conventional control. Inthis paper

a FCS-MPC controller is designed for the three-phase voltage power electronic inverter. First-ly

the predictive model expressed by vector is set up with aim of achieving non-linear control in simpleand intuitive method and

at the same time

also improving its response speed. Then

complex field cur-rent vector signal is taken as basic design objective function

which

at the time of omitting coordinate con-version

avoids the over current issue. Finally

as for the issue of complex calculation

a neighbouring vec-tor selection principle is proposed

which decrease lots of calculation online. It is shown by the simulationresult that FCS-MPC for power electronic device can improve its dynamic response speed

the establishedneighbouring vector selection principle can

at the premise of assuring output current quality

reducegreatly the calculation of the controller and lay a foundation for the hardware implementation.
