Hierarchical Control of Nonlinear Active Four-Wheel-Steering Vehicles
Energies, 2018 A new type of hierarchical control is proposed for a four-wheel-steering (4WS) vehicle, in which both the sideslip angle and yaw rate feedback are used, and the saturation of the control variables (i.e., the front and rear steering angles) is considered.
