The present article compares the Proportional Directional Control Valve (PDCV) and Orbitrol Valve coupled to the steering system of the articulated steered vehicles. Simulation models of both the PDCV and orbitrol valve coupled steering systems are developed in a MATLAB environment, and results are well-validated with the experimental data. Comparison analysis has been performed between the PDCV and orbitrol valve-controlled steering system by controlling the desired position demand using a conventional PID controller. From the comparative study, it is observed that the orbitrol valve provides almost 50% energy reduction compared to PDCV, but the valve response is low compared to PDCV. Moreover, the steering response provided by the orbitrol valve is quite enough for performing steering operations in mining conditions. Overall, the orbitrol valve offers more efficient and smooth steering than the PDCV valve. The future work of the present study extends to the development of autonomous steering operation using an orbitrol valve-operated articulated steering system.

You can write a PREreview of Comparative Study on Performance and Energy Efficient Operation of the Steering Valves Used in Articulated Steering System. A PREreview is a review of a preprint and can vary from a few sentences to a lengthy report, similar to a journal-organized peer-review report.
