Abstract: This paper presents the design and implementation of a PLC-based automated system for controlling 10 stroke cycling operations in commercial vehicle testing using an LVDT position sensor. An Omron PLC serves as the central controller while a Linear Variable Differential Transformer (LVDT) provides precise real-time displacement feedback through a closed-loop control mechanism. The system governs the forward and reverse motion of a pneumatic actuator, with an integrated counter ensuring exactly ten stroke cycles before automatic shutdown. Testing confirmed high accuracy, repeatability, and reliability, establishing the system's suitability for industrial automotive testing applications.
