  • Cabin pressure control system with multiple outflow valves and method of calibrating the outflow valve position feedback during flight
    Patent number: 8694181
    Abstract: A method of calibrating an outflow valve on an aircraft may include determining if the aircraft has reached a predetermined cruise condition. The outflow valve may be moved until a closed position is reached, if the aircraft has reached the predetermined cruise condition. An actual position feedback value of the outflow valve may be determined while the aircraft is in the predetermined cruise condition. An offset calibration factor may be determined from the actual position feedback value of the outflow valve relative to a theoretical value.

  • Cabin pressure control system and method that implements high-speed sampling and averaging techniques to compute cabin pressure rate of change
    Publication number: 20070010188
    Abstract: An aircraft cabin pressure control system and the method implement a technique that oversamples and filters a sensed cabin pressure signal, and then differentiates the oversampled and filtered pressure signal to generate cabin pressure rate-of-change. The oversampling and filtering technique removes circuit and sensor induced noise from the cabin pressure signal, and results in cabin pressure rate-of-change values with less noise than currently known systems and methods.

  • CABIN PRESSURE CONTROL METHOD AND APPARATUS USING ALL-ELECTRIC CONTROL WITHOUT OUTFLOW VALVE POSITION FEEDBACK
    Publication number: 20050153648
    Abstract: A pressure control system including an inflow unit for admitting pressurized air into a cabin, an outflow unit including a motor for operating a valve to discharge air from the cabin at a predetermined rate based on an motor control signal that sets the motor speed, a control unit, and an air pressure sensor within the cabin for determining a pressure signal. The control unit receives the pressure signal and computes a pressure rate of change error signal to set the motor control signal. The outflow unit, control unit, and air pressure sensor form a feedback control loop independent of motor speed, valve speed, or valve position feedback.
