ICA based Adaptive Disturbance Cancellation for MIMO System with Unknown Dynamics

This paper proposes a method for canceling an additive disturbance at the outputs of a MIMO system with unknown dynamics; i.e. the designer has no knowledge of the system except for observation of some inputs and noisy outputs. To counter the disturbance, a modified independent component analysis method is first used to estimate the unknown disturbance and its dynamic. Then the disturbance contribution is canceled from the measured outputs
