| Abstract |
Information about the back-emf of an induction motor can be used in various control and
estimation schemes. This paper proposes a simple method for fast tracking of the back-emf based on
the evaluation of the derivative of the stator current during a PWM switching period. No prior
knowledge of motor parameters is needed. Simulation results show that the estimated back-emf is in
close agreement with the actual one even under transient conditions. |
