Robust H∞ state feedback control for handling stability of intelligent vehicles on a novel allwheel independent steering mode

We propose an H∞ dynamics controller for an all-wheel independent steering. A norm-bounded method is used to describe the uncertainties in the system. A new reference model aimed at minimising the yaw rate and making the sideslip angle remain the same as the target sideslip angle is proposed; this will help especially when a vehicle changes lanes. Simulation and experimental results indicate that the controller can help improve the handling stability and correct directional problems when the vehicle's direction is changed by the steering angle.
