要本論文旨在研制一套光電成像跟蹤系統(tǒng)，該系統(tǒng)能在實驗室條件下實現(xiàn)對動目標的實時跟蹤，為理解光電成像跟蹤系統(tǒng)的構成和實際應用提供實驗平臺和原理演示平臺。本文闡述了光電成像跟蹤系統(tǒng)原理與組成，論述了光電成像跟蹤系統(tǒng)的設計和實現(xiàn)。 針對跟蹤系統(tǒng)設備和系統(tǒng)指標要求，確定了跟蹤控制系統(tǒng)結構：控制系統(tǒng)由上位機和下位機兩級控制系統(tǒng)組成，上位 PC機對 CCD相機采集的圖像進行光電圖像處理并提供人機界面，下位機采用基于DSP芯片的實驗系統(tǒng)實現(xiàn)二維轉(zhuǎn)臺的實時控制，二者之間通過 RS232通信協(xié)議進行命令和數(shù)據(jù)的通訊。結合轉(zhuǎn)臺驅(qū)動元件——步進電機的矩頻特性，對轉(zhuǎn)臺采用自適應控制策略，使二維轉(zhuǎn)臺的水平速度和垂直速度動態(tài)地改變，使得轉(zhuǎn)臺實時的跟蹤目標，實現(xiàn)了高精度跟蹤控制。關鍵詞：光電成像跟蹤 DSP 自適應控制 變速控制 串行通信
