Abstract
A hydraulic circuit and optimal control law for controlled fluid recirculation have been devised to reduce energy consumption from that of a conventional four-way servo valve. The simulations for moving a 100 lb. mass horizontally 5 inches in 0.210 sec. show an energy savings of 28%. The control history was simplified and implemented on a breadboard system and the successful operation verified experimentally.
