Abstract
A simple robust yaw controller for the nonlinear single-trackmodel is designed, making use of active differential and activeroll control systems. Robustness is studied for uncertainties inseveral model parameters, namely the vehicle longitudinalvelocity, the road adherence coefficients and the hand wheelangle. Constructive nonlinear dynamics are employed for thecontroller design. The controller parameters are selected bysolving an optimization problem. Stability of the solution isguaranteed by constraints that ensure a minimal distance betweenthe nominal operating point and a stability boundary in the spaceof uncertain parameters.
