Abstract

A simplified model of the steering system incorporating vehicle dynamics is analyzed based on the structure of the Electric power steering (EPS) system, and a linear quadratic regulator controller is proposed by taking the steering wheel angle, yaw rate and the sideslip angle as the optimization object. Additionally, a state-space observer is designed to estimate the sideslip angle which is difficult to measure directly. Finally the simulation and experiment of vehicle snaking test shows that the control can improve the steering characteristics and handing stability effectively.
