What can be a result of actuator hysteresis?

Actuator hysteresis refers to the phenomenon where there is a difference in the output of an actuator when the input is increased compared to when it is decreased. This occurs due to factors such as mechanical friction, material properties, and system design. As a result, when the input signal to the actuator changes, the output may not respond in a linear or consistent manner, leading to variability in its performance.

This variability can manifest as differences in position, speed, or force produced by the actuator for the same input settings, which can hinder precision control in pneumatic systems. It's essential for engineers to understand and account for hysteresis to improve the reliability and accuracy of actuator systems, particularly in applications where precise positioning and responsiveness are critical.
