Abstract
At least some embodiments of the present disclosure are directed to distributed pump architectures used in control systems for multifunctional machines. In some cases, a control system for a multifunctional machine includes three or more control circuits. At least two of the control circuits each has a hydraulic fluid pump and each of the pumps is controlled by a different control circuit. At least two of the hydraulic fluid pump have different flow rates.
Claims20
A control system for a fuel power system, comprising:
- a first control circuit comprising a first pump and configured to control a first hydraulic fluid flow from the first pump to a first discrete set of one or more functional devices,
- a second control circuit comprising a second pump and configured to control a second hydraulic fluid flow from the second pump to a second discrete set of one or more functional devices, and
- a third control circuit comprising a third pump and a hydraulic motor and configured to control a third hydraulic fluid flow from the third pump to a third discrete set of one or more functional devices, the hydraulic motor configured to control a rotation movement,
- wherein a first flow rate of the first hydraulic fluid flow is different from a second flow rate of the second hydraulic fluid flow,
- wherein the first flow rate of the first hydraulic fluid flow is different from a third flow rate of the third hydraulic fluid flow, and
- wherein the second flow rate of the second hydraulic fluid flow is different from the third flow rate of the third hydraulic fluid flow.
