Abstract

This paper presents an experimental investigation into the frequency response of an electropneumatic positioning system, which includes a rodless pneumatic cylinder and four 2/2-way high speed pneumatic valves operated via pulse width modulation. The experimental procedures are captured and analyzed in real-time using a dedicated virtual instrument. The amplitude and phase Bode plots for the electropneumatic positioning system were obtained through experimentation and subsequently analyzed, leading to the identification of the system's critical frequency. The findings are illustrated through various graphs.
