| Abstract |
This paper describes a method of deriving frequency characteristics of PMSM current control systembased on Model Predictive Control (MPC). MPC controller predicts the current behavior using the math-ematical model of PMSM and directly selects the optimal switch state based on evaluation of thesepredicted results. So, we have focused the possibility of MPC, which makes it possible to drive ma-chines seamlessly between linear operating region of inverter and the overmodulation operating region.But, MPC is a nonlinear control system, so its frequency characteristics are unknown. In this paper, wederive MPC's frequency characteristic approximately through simulation to realize its frequency domaindesign. |
