Exact Input-Output Linearization for a Trailer Steering Controller

In this paper the authors present how the exact input-output linearization technique can be used for a nonlinear trailer steering controller in order to improve the maneuverability of heavy commercial vehicles with semi-trailers. In order to overcome modeling uncertainties and to increase the robustness, the exact input-output linearization is extended with a sliding mode control approach. This paper focuses on the applicability of the exact input-output linearization. It is analyzed, whether the relative degree is well-defined with respect to the variation of typical vehicle parameters.
