The modeling and control of a variable speed cascaded doubly fed induction generator feeding an isolated grid in aircraft application is presented. Despite the complexity of the generator an efficient controller can be elaborated based on the theory of a unified reference frame vector representation. An indirect decoupled vector control of terminal voltage is implemented using field orientation techniques...
In this paper, on the basis of vector control, Extended Kalman Filter (EKF) was employed to estimate stator winding resistance, rotor flux-linkage due to permanent magnet and temperature rise in stator winding and rotor magnet of AC PMSM. Identification model of different parameter was established in rotating reference frame and MATLAB/SIMULINK was used to do simulation experiments. The theoretical...
