Development of Stroke Sensing Cylinder Using Magnetic Sensor and Its Performance Estimation

자기 센서를 이용한 스트로크 센싱 실린더의 개발 및 성능평가

We developed a part of storke sensing cylinder using magnetic sensor and estimated is performance. In this paper, for the performance estimation of stroke sensing cylinder. We consist of hydrallic system using solenoid valve with ON/OFF motion. In order to the control of solenoid valve for the position control of cylinder rod, PWM (Pulse Width Modulation) method which modulates time pulse width in proportion to error was used. A performance of cylinder rod with magnetic scales was evaluated by its hydraulic system.
