Abstract
A method for compensating a steering system exhibiting dead-zone characteristics estimates the dead-zone parameters of the steering system and establishes a dead-zone inverse function utilizing the estimated parameters. The dead-zone inverse is utilized to transform steering orders in the dead-zone. Parameters of the dead-zone inverse are continuously up-dated with the utilization of the transformed steering order, the existing dead-zone parameters, and the present heading.
