Path Following of Autonomous Vehicles in the Presence of Sliding Effects

In this paper, a new controller for the path-following problem of a car-like autonomous vehicle is proposed. This controller is based on a new transformation that, for the case of roll with no slip, transfers the model to a chain form. However, in many practical cases, due to the strong effects of tire slip angles, a roll with no slip assumption is invalid. To cope with the presence of slip, a novel controller is proposed. The new method is based on a vehicle kinematical model, where the tire slip angles are taken into account. The control design method utilizes a peak-to-peak criterion and linear matrix inequality (LMI) tools to attenuate tire slip angle effects on the closed-loop performance.
