| Abstract: | In order to improve the reliability and adaptability of control system for induction motors, a modified speed sensorless stator flux orientation vector control system is presented. The stator flux is estimated by adaptive compensated voltage model, and the speed is estimated with PI adaptive method. The simulation and experiment show the good performance for the system in stationary state identification accuracy and robustness. |
