Abstract
At least one example embodiment discloses a method of controlling steering of a vehicle. The method includes identifying a reduced-order vehicle model, the reduced-order vehicle model representing a vehicle transfer function in which a least one high-frequency pole is removed. The method further includes generating target closed loop pole locations based on at least one user preference parameter. The method further includes determining calibration parameters that place closed loop poles of a composite system at the target closed loop poles. The composite system in this context includes the reduced-order vehicle model and a steering control system. Finally, the method includes controlling the steering using the steering control system configured using the calibration parameters.
