Control valve actuation

A method for actuating of a control valve of a hydraulic system, the method comprising:

• receiving a first input from a variable speed component;
• receiving a second input from the variable speed component;
• comparing the second input to a predetermined limit;
• enabling frequency tracking if the second input is within the bounds of the predetermined limit, wherein frequency tracking includes:
• determining a frequency of the variable speed component based on the first input;
• selecting a control valve actuation frequency for a control valve of a hydraulic system, wherein the control valve actuation frequency is based on the frequency of the variable speed component;
• actuating the control valve in accordance with the control valve actuation frequency.

A hydraulic system comprising:

• a power source;
• a fluid displacement assembly coupled to the power source;
• a plurality of actuators in selective fluid communication with the fluid displacement assembly;
• a plurality of control valves adapted to provide selective fluid communication between the fluid displacement assembly and the plurality of actuators;
• an electronic control unit adapted to actuate the plurality of control valves, wherein the electronic control unit:
• receives a rotational speed of the power source;
• determines a firing frequency of the power source based on the rotational speed;
• selects a frequency of a pulse width modulation signal for the plurality of control valves based on the firing frequency of the power source;
• and
• actuates the plurality of control valves in accordance with the frequency of the pulse width modulation signal.
