CONTROL THE ROAD WHEEL STEERING ANGLE OF ELECTRO-HYDRAULIC STEER-BY-WIRE SYSTEM USING RISE CONTROLLER

Abstract

Steer-by-Wire system is a great development compared to mechanical,
hydraulic or electric steering systems, because of its ability to improve vehicle
safety, comfortability, and flexibility for drivers, as well as the requirements for a
self-driving car in the future. This paper introduces a continuous robust control
method using RISE controller for the steering wheel mechanism of the electrohydraulic SBW system to drive the front wheels to track the reference trajectory
from the handwheel. The control efficiency of the introduced controller is
illustrated by several Matlab simulations at different vehicle speeds and on two
different road conditions as dry and wet asphalt road surfaces.
