1、碩士論文基于刪和FPGA的嵌入式敷控系統(tǒng)研究摘要隨著現(xiàn)代控制理論在機(jī)電技術(shù)領(lǐng)域的不斷發(fā)展,多電動(dòng)機(jī)協(xié)調(diào)控制技術(shù)在機(jī)電控制系統(tǒng)中得到廣泛的應(yīng)用,給嵌入式系統(tǒng)的數(shù)控應(yīng)用提供了巨大機(jī)遇。傳統(tǒng)的伺服運(yùn)動(dòng)控制根難在處理大數(shù)據(jù)量、復(fù)雜算法時(shí)保證系統(tǒng)的靈活性和實(shí)時(shí)性。嵌入式系統(tǒng)是近年來(lái)發(fā)展起來(lái)的以應(yīng)用為中心并且軟硬件可裁剪的實(shí)時(shí)系統(tǒng),它的特點(diǎn)是高度自動(dòng)化,響應(yīng)速度快等,非常適合于要求實(shí)時(shí)的和多任務(wù)的場(chǎng)合。本文以嵌入式數(shù)控系統(tǒng)為項(xiàng)目背景,研究設(shè)計(jì)了一種基于ARM和FPGA的嵌入式數(shù)控系統(tǒng)的方案。設(shè)計(jì)中,通過(guò)Quartus11,ModelS
