Abstract :
This paper is concerned with Fault Detection and Isolation for induction motors. A new procedure for the calculation of the ARR (Analytical Redundancy Relations) is presented. This method is based on the elimination of the unknown variables (states, unknown inputs, ...) in the model equations. Simulation results are presented in normal situation and in presence of a speed sensor fault.
