Method of controlling a fluid |
摘要 |
A method of controlling a fluid in a life support system including at least one of a G-suit and a counterpressure garment including utilizing a control system comprising a control valve having a moveable part which is moved by an actuator in response to an input to the control system to operate the valve to bring a parameter of the fluid towards a desired value, the input being conditioned to provide a control signal to cause the actuator to move the moveable part of the valve and wherein the method comprises conditioning the input by comparing the input with reference information relating to the position of the moveable part of the valve, and when the comparison indicates that the position of the moveable part of the valve is not at a desired position, issuing the control signal incrementally to move the moveable part and updating the reference information so that the updated reference information is available for future comparison with the input.
