Improving machine efficiency remains a top priority in the industrial and academic communities given the ever increasing demand on fossil fuels and their skyrocketing prices. Pump displacement controlled (DC) actuation is an energy efficient alternative to traditional valve controlled actuators. The technology has shown significant fuel savings on mobile machinery when used for the working hydraulics (implement) functions of such machines. However; DC actuation has not been investigated for use on mobile machinery chassis systems; namely power steering. In this paper; a novel closed-circuit displacement control system architecture is devised to perform the functions of a power steering system used on articulated steering vehicles. A high-fidelity multi-domain dynamic model of the vehicle is generated to corroborate concept feasibility; perform system sizing and analysis; and predict overall performance. Simulation results have shown that a displacement controlled power steering system is realizable despite of certain challenges; which upon further ongoing research will be brought to life and tested on a prototype machine
