Abstract
A steering control system and method for automated steering of work vehicles that adapts to nonlinearities and uncertainties of steering mechanisms including a tolerance control law, a dynamic control law, and a saturation control law selected and executed in real time based on the magnitude of steering angle error, steering mode command, and manual override signal in real time. The dynamic control law includes a dynamic compensator having a double compensation zero, an integral, and a compensation gain, and further includes a deadband compensator and a control signal limiter.
