Item type:Publication, Access status: without files , Torque vectoring with a feedback and feed forward controller : applied to a through the road hybrid electric vehicleThis paper concentrates on the torque commands for electric propulsion motors in a through the road hybrid electric vehicle. By using a linear quadratic gaussian controller, a flat feed forward controller and a linear desired value generator the lateral vehicle dynamics are influenced. Understeering, oversteering, agility and cornering speed can be optimized by proper controller design. A 14 degree of freedom vehicle model with a Dugoff tire model is used to simulate the vehicle behaviour. The simulation results show improved vehicle dynamics and increased handling for the driver compared to a equal distributed torque command.Publicationtype: Conference Paper30 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Two-degree-of-freedom LPV control for a through-the-road hybrid electric vehicle via torque vectoringThis paper presents an application of linear-Parameter-Varying (LPV) control to solve the torque vectoring problem of a through-the-road hybrid electric vehicle (TtR-HEV). To achieve high performance both in reference tracking and disturbance rejection, a two-degree-of-freedom LPV self-scheduled controller is synthesized by using mixed sensitivity loop shaping. The controller is based on a single Lyapunov function and guarantees stability and a level of control performance for all admissible trajectories of varying parameters. Moreover, an anti-windup control scheme is derived by employing a two-step design procedure. Finally the designed controller is tested in various driving maneuvers and compared with a flatness-based controller.Publicationtype: Conference Paper37
