沖床在不同速度下的剎車(chē)角度如何跟據電機頻率計算，據說(shuō)方法是分5段0-10hz，10-20hz，20-30hz，30-40hz，40-50hz 然后用折線(xiàn)擬合，還有一種辦法是用二項式直接擬合，請大神指教如何才能計算出剎車(chē)角讓滑塊每次都準的停到上死點(diǎn)？還看到文獻說(shuō)每次記錄所停角度偏差，下次修正，具體算法是怎么樣PLC編程的，不吝賜教！

不同的速度還有不同的制動(dòng)角度嗎？我一直以為都是一樣的哎。
我家里電腦上有多種壓機的程序�；厝タ梢詭湍憧匆幌�。
修了多年壓機的我一直認為剎車(chē)角度是固定不變的呢？

慚愧慚愧。。。
