| Abstract: | This paper presents a kind of stroke sensing cylinder based on inside magnetic measurement. The key technique of stroke sensing cylinder-measurement system is studied, and a frame superimposed scale coding is presented. Through calculation on varied parameters, a group of suitable parameter is found out. To remove the resulting errors come from the change of gap between the piston rod and sensor, a signal processing method accompanied with machine learning process is investigated. The experimental results indicate that the technique in this paper is proper. |
