Motion Control of a Single Rod Cylinder-Load System Driven by a Proportional Directional Control Valve

비례방향제어밸브에 의해 구동되는 차동 실린더 부하계의 운동제어

This paper deals with the issue of motion control of a single rod cylinder-load system using simple adaptive control (SAC) method. Prior to controller design, the experiment of open-loop response has been performed. Based on it, design parameters of transfer function are obtained. The effect of parallel feedforward compensator has been investigated by computer simulation, suppressing the oscillatory motion. Through experiments it is conformed that the SAC method gives good tracking performance compared to the PD control method.
