系統(tǒng)是用來(lái)準(zhǔn)確的跟隨或復(fù) 現(xiàn)某個(gè)特定過程的反饋控制系統(tǒng)，又被稱為隨動(dòng)系統(tǒng)。論文中給出了各個(gè)模塊的 VHDL 代碼，以及這些模塊相對(duì)應(yīng)的時(shí)序仿真。 本設(shè)計(jì)以 FPGA 現(xiàn)場(chǎng)可編程邏輯器件做為中央控制器件， 對(duì)信號(hào)進(jìn)行處理，速度快，可靠性高；并以 AD1674 為數(shù)據(jù)采集系統(tǒng)的核心部件；硬件驅(qū)動(dòng)電路采用大功率 MOSFET 管所構(gòu)成的單極可逆 H橋電路 ， 并采用 PWM 方式驅(qū)動(dòng)電路 ?，F(xiàn)在社會(huì)隨著 EDA 技術(shù)的不斷發(fā)展，實(shí)現(xiàn)電機(jī)數(shù)字控制的方法也隨之發(fā)生
