Abstract:
1. A method comprising: assigning a priority level so that it is associated with each of a plurality of hydraulic loads; formulating a pulse width modulated control signal based on the assigned priority levels; transmitting the control signal to a plurality of digital valves, each valve operable to selectively fluidly connect at least one of the hydraulic loads to a pressure source; sequentially actuating at least a subset of the digital valves in response to the control signal; actuating the valves in sequential order based on the assigned priority level of the associated hydraulic load; basing each assigned priority level on at least one of a pressure requirement and a flow requirement of the specific hydraulic load; and sequentially actuating the valves commencing with the valve associated with the hydraulic load having one of a highest pressure requirement and a lowest pressure requirement, and proceeding in sequential descending or ascending order, respectively, based on the pressure requirements of the remaining hydraulic loads.
