Induction motor drive, model reference adaptive system estimation sensor less control scheme.


This paper describes a Model Reference Adaptive System (MRAS) for speed control of the Induction Motor drive (IM) without a speed sensor. In this scheme reduced-order Flux Observer is used instead of the Full-order Flux Observer, a reduced order flux observer is used for estimate the IM rotor speed, and these are used as feedback signals for the Field Oriented Control (FOC), which is a widely used control method for Induction Motor drive (IM). In comparison with the full order observer, the proposed method consumes less computation time and illustrated better speed performance. Simulation results shows that the proposed scheme can estimate the motor speed under various adaptive PI gains and estimated speed can replace to measured speed in sensorless induction motor drive.
