This paper considers robust controller design methods applied to the problem of an automatic steering system for tow-vehicle/trailer combinations. An Inverse Linear Quadratic Regulator (ILQR) approach is followed. It combines pole assignment methods with conventional Linear Quadratic Regulator (LQR) methods. It overcomes two problems associated with these separate methods. It overcomes the robustness problems associated with pole placement methods, and overcomes the trial and error required in the application of the LQR method. Moreover, methods for obtaining robust observer performance are considered. A Kalman filter is used as the observer, but it is modified by using the loop transfer recovery (LTR) technique. This technique recovers the robustness of the full-state feedback regulator. The combination of the robust regulator and robust filter is called a ILQG/LTR controller.
