| Abstract: | In this paper, a robust adaptive control algorithm for
speed sensorless induction motor drive is presented.
The main feature of this control algorithm is that minimum
synthesis is required to implement the proposed
strategy. It is known as model reference adaptive controller
(MRAC). The MRAC appeared to be robust in
the fact of totally unknown plant dynamics, external
disturbances and parameter variations. The induction
motor stator resistance variations eect on the
rotor speed are rejected by the MRAC controller due
to its robustness. However, the performance of the
Indirect Stator Field Oriented Control (ISFOC) are
shading o. It is so because the reference commands
computation of the ISFOC are based on the induction
motor model, which includes that resistance. Therefore,
a combination of three observers is used : a Luenberger
observer to obtain the rotor ux and a two
MRAS observers for rotor speed and stator resistance
estimation. Digital simulation results are presented
to highlight the improvement in performances of the
overall proposed control scheme.
