Disturbance Rejection System Based on Independent Component Analysis

Abstract

This paper proposes a method for identifying and suppressing unknown disturbances based on independent component analysis. Under the assumption that the sources of disturbance and control inputs are mutually independent, the proposed method makes it possible to estimate the transfer functions from disturbance sources to signals to be controlled. Two types of disturbance suppression control systems using the disturbance model are introduced and the effectiveness of these control systems has been demonstrated through some numerical simulations.
