simulation and modeling of a hydraulic cylinder

1 次查看(过去 30 天)
when the hydraulic cylinder reaches the end of its travel, it stands and swings. but in reality it is totally different. i have made two attempts. the first one i operated the directional control valve by a Step. it remains open although the hydraulic cylinder reaches its point.
in the second attempt i have a feedback between the position of the cylinder and the indicated step. I have another question.i have to hand in my master thesis soon, i have other questions. please help me....
