Abstract :
Unknown input observers (UIO) are able to estimate perfectly the state of a system, despite completely unknown input perturbations. In this paper the experimental evaluation of an unknown input observer suitable for flux estimation for induction motors taking the load torque as unknown input is presented. Experimental results on a semi-industrial setup are given.
