Self-tuning Vector Control System of Induction Machines Based on Dual EKF

摘要

Dual EKF which is suitable for simultaneously on-line estimating states and parameters of nonlinear systems is applied to the rotor resistance and rotor flux on-line simultaneous estimation problem of vector control system of induction machines. Based on Dual EKF, a self-tuning vector control system with higher performances is established. Simulation results show that the proposed scheme is effective at full speed range and under various operating conditions.
