Composite Model Reference Adaptive Speed Sensorless Vector Control
Flux linkage model and reactive power model are often used for model reference adaptive speed estimation because of their simple structure and good estimation performance.In view of the dynamic and steady state problems of flux linkage model and reactive power model,a composite model consisting of reac-tive power,flux linkage and switch function was proposed by analyzing the difference of flux accuracy of dif-ferent models,which could achieve accurate velocity estimation in both dynamic and steady state processes.Through Matlab/Simulink simulation and real experiments,it was proved that the composite model had good dynamic tracking performance and excellent steady-state performance.
