Abstract :
A robust high speed algorithm, RHSA, applied in the field oriented vector control strategy, is presented in this paper for the PMSM sensorless control loop. The present algorithm, RHSA, is formed for online generating the direct and quadrature reference stator current. Based on the fuzzy logic controller and the field weakening principle, the RHSA is constructing. The sliding mode, based on Lyapunouv stability criterion, is used for the online speed estimation. The Robustness of the global control scheme is verified through computer simulation using matlab/Simulink software.
