Pneumatic Pressure Control Using on‐off Valves with Pulse Width Modulation

Chemical Engineering &Technology, Volume 46, Issue 1, Page 21-28, January 2023., 2023
To reduce hysteresis and improve accuracy of a two‐stage airplane flow valve, an on‐off switching valve with its pulse width modulation (PWM) control is proposed as a first stage in replacement of a currently used servomotor‐controlled valve. A method is introduced for properly choosing the on‐off valve and tuning the PWM parameters.
