Abstract
An airflow control system includes a valve including a valve disk rotatable within a flow control duct and a valve actuator connected to the valve disk. The valve actuator is operable to adjust a position the valve disk. A pneumatic controller is configured to regulate a pressure within the flow control duct downstream of the valve disk by adjusting the position of the valve disk when the pressure within the flow control duct downstream of the valve disk exceeds a regulation pressure set point. A torque motor is fluidly connected to the valve actuator and a digital controller is operably coupled to the torque motor. The digital controller is configured to regulate the pressure within the flow control duct downstream of the valve disk independently from the pneumatic controller.
