Abstract :
A new electromagnetic state observer, based on the concept of loop transfer recovery (LTR), is presented. The simplicity of induction motor electromagnetic dynamics in a complex variable has made it possible to deduce an observer which presents an optimal response to perturbations located at the input of the plant and almost insensitive to stator resistance and inductance variations
