| Abstract |
Finite-control-set model predictive control (FCSMPC) has emerged as an effective solution tooperate high-power wind turbine based on neutralpoint-clamped (NPC) converter. However, modeling uncertainties can degrade the performance of MPC. This paper first analyzes the impact of grid parameter error on current prediction accuracy and develops a robust FCS-MPC strategy combined with Extended Kalman Filter (EKF) parameter observer. Simulation results are given to validate the effectiveness of the proposed control structure to mitigate filterinductor parameter mismatch. The proposed approach aims to enhance the performance of MPC against grid filter variations. |
