Abstract :
This paper deals with programmable LPF (low pass filter) based stator flux estimation for speed sensorless induction motor drives. This algorithm is proposed to solve the dc drift problem and errors due to stator resistance variation associated with the ideal integrator and a LPF. This algorithm has pole/gain compensator to estimate stator flux over wide speed range. Accordingly, the severity of drift problem is much reduced and the stator flux is exactly estimated in the wide speed range. The validity of the Programmable LPF algorithm is verified by rotor flux oriented speed sensorless vector control of a three phase induction motor through simulation and the simulated results are verified in an TMS320F2812 DSP processor.
