  2. And so on, the mathematical model and transfer function of the tracking system are built, and the feasibility of the tracking control system design is demonstrated. furthermore, the static error of the system with a unit incline input is deduced. a majority of model of unit is based on analytics, so the general model can apply to other optical intersatellite communications systems

    在此基礎上，將atp跟蹤控制子系統視為線性定常系統，通過解析法和實驗法對子系統的各個控制環節的單元器件進行合理建模，得出整個環路總的開環及閉環傳遞函數，論證了本課題所設計的atp跟蹤控制環路的可行性及其視軸輸入為斜坡信號時的理論穩態誤差。
  3. Sercos interface, a serial real - time communications system, is an connection of nc controller, drives, motion unit and i / o unit of nc control system, which are connected by a fiber optical ring

    Sercos介面是數字控制系統中連接數字控制器、驅動器、執行機構以及輸入輸出部件，在彼此間進行實時通訊的國際標準。 sercos介面採用光纜將控制部件連接在一起，構成一個封閉的環路。
  4. Optical code division multiple access ( ocdma ) is a communication mode which introduces the code division multiple access ( cdma ) technology into optical fiber communication system. besides providing asynchronous communications access, ocdma system has many advantages, such as high capacity, security against interception, suppression of narrow band disturbances, capability in forming variable bit rate networks and multi - rate networks. it implies a great challenge for the development of future communication networks, especially all optical networks

    光碼分多址（ ocdma ）是將碼分多址（ cdma ）技術與大容量的光纖通信技術相結合的一種通信方式，其主要優點表現在如下幾個方面：允許多個用戶隨機地接入同一通道：可構成真正「透明」的全光通信網路；具有良好的安全性；允許可變速率或多速率傳輸，並可同時提供多種業務支持；具有優良好的抗干擾能力，並能夠充分地利用石英光纖的可用帶寬。
