Abstract : An experimental hydraulic fluidic control unit has been developed that will detect and correct angular variations, such as those experienced by a bulldozer grader blade. The developmental testing was accomplished in two phases. The first phase developed a hybrid electrical/hydraulic system, while the second phase eliminated the electrical interface. The necessary modifications to the equipment were accomplished at CEL. The fluidic control unit requires only an input pressure source, which is normally available from the hydraulic control system of the vehicle. Some additional development work remains on fine tuning the dynamic response of the control unit.
