各位大俠，我做了個(gè)項目，關(guān)于8個(gè)油缸同步控制，每個(gè)缸上都有一個(gè)位移傳感器4-20MA 信號的，這幾個(gè)缸分4個(gè)主缸和4輔缸 要舉升一個(gè)400噸的平臺上升和下降，要求平臺平穩上升下降，我做了一部分，上升通過(guò)通過(guò)四個(gè)主缸先升3毫米停下在4輔缸在升3毫米反復交替進(jìn)行，效果還可以，我用同樣的方法做下降，結果就亂套啦，因為下降時(shí)平臺太重只要閥一打開(kāi)，平臺下降太快3毫米跟本控制不住，有多有小，結果平臺就傾斜啦，各位有沒(méi)有做過(guò)這方面的提供點(diǎn)經(jīng)驗
