Abstract
The dynamic characteristics of an Electro-hydraulic (EH) steering system plays an important role in realizing an accurate steering control for an automatically guided vehicles. In this paper, a mathematical model has been developed for EH steering system that includes EH servo valve with mechanical feedback, steering actuation cylinders and associated steering linkages. A proportional-integral controller has been designed to improve the dynamic performance of EH steering system for off-road vehicles. The simulated system models using SIMULINK were validated using experimental tests. The control of steering angle using the proposed proportional-integral controller has been demonstrated for different soil conditions.
