Abstract
In one aspect, a variable pressure actuation system is provided. The variable pressure actuation system includes an actuator configured to control a variable geometry device, and a fluid line fluidly coupled to the actuator. The fluid line is configured to supply a pressurized fluid to the actuator to facilitate controlling the variable geometry device. The system further includes a load feedback device coupled to the actuator, the load feedback device configured to measure a load placed on the actuator by the variable geometry device.

A variable pressure actuation system comprising:
- an actuator configured to control a variable geometry device;
- a fluid line fluidly coupled to the actuator, the fluid line configured to supply a pressurized fluid to the actuator to facilitate controlling the variable geometry device;
- and
- a load feedback device coupled to the actuator, the load feedback device configured to measure a load placed on the actuator by the variable geometry device.
A method of scheduling pressure in a variable pressure actuation system having an actuator configured to control a variable geometry device, a fluid line fluidly coupled to the actuator, and a load feedback device coupled to the actuator, the method comprising:
- measuring, with the load feedback device, a load placed on the actuator by the variable geometry device;
- and
- scheduling a fluid pressure level in the fluid line based on the measured load.
