The rotor speed flux information are most important in the speed sensorless vector control. Therefore in the paper using current and voltage model obtained correctly flux information in a induction motor. Voltage model realized low pass filter instead of integrator, current model realized used of current equation. And current and voltage model estimated flux composed of PI controller.
For compensation of estimated flux error flux compensation algorithm using exactly, rapidly rotor flux obtained for compensation of estimated flux error.
Proposed control system used TMS320C31 DSP for high speed processing. The effectiveness of the proposed method is verified by simulation and experimental results. This method shows highly characteristic speed estimation highly flux estimation and stable, robust character of load regulation.
