Robust Predictive Control Scheme for Permanent-Magnet Synchronous Generators Based Modern Wind Turbines

In this article, a deadbeat predictive control (DB-PC) strategy for permanent-magnet synchronous generators (PMSGs)-based modern wind turbines is proposed. The main advantages of the DB-PC technique are its excellent dynamics and constant switching frequency. However, idea obtaining actuation voltage next sample from mathematical model generator. Therefore, highly sensitive to mismatches in parameters PMSG. order obviate problem, disturbance estimator (extended Kalman filter (EKF)) employed work enhance robustness proposed scheme by estimating total due parameter adding it calculation voltage. Furthermore, same EKF observe rotor speed position PMSG, i.e., mechanical sensors not required. Moreover, able reduce harmonic distortion stator currents implemented laboratory. experimental results proved superiority over traditional technique.
