N2 - It is well known that modern induction motor control rely on a good dynamic model of the motor. Full state variable information together with exact parameter knowledge is needed. The aim of this work is to fulfill these needs by use of a novel nonlinear observer structure based on the backstepping princip. A full proof for convergence of states is presented together with a stability proof for the parameter estimates. When the system is persistently excited simulations and experiments show convergence of the parameters. The observer is used in a Rotor Field Oriented Control strategy and verified by experiments.
