An iterative system inversion technique

An inversion iterative algorithm for discrete-time non-linear systems is pr esented. The algorithm is tuned depending on system characteristics. Under the assumption that the system inverse exists, the iterative algorithm cons tructs the system inverse by attempting to achieve on-line the perfect trac king. The inversion process is based on the observation of the input-output pairs. The resulting control scheme requires a very low a priori knowledge of the system dynamics. Moreover, low-engineering efforts are needed to ap ply the control scheme to a particular control problem or to modify it in o rder to accommodate changes in the physical system.
