  1. Firstly the pwm implementation of relay is given. in succession the characteristic of extruder barrel is obtained by measuring their step response. at last the implementation of pid and fuzzy control are studied in detail and the results of the experiment are presented

    首先對料筒特性進行了測試研究，介紹了繼電器pwm控制的實現方法，然後分別進行了積分分離pid及模糊變系數pid控制策略的研究。
  2. With the advantages of high gain and output power, low noise, wide bandwidth as well as no relation with polarization, edfa changes the traditional optical - electrical - optical relay mode step by step in many fields, and becomes an indispensable device in modern optical communication systems. it saves the expensive cost in optical - electrical transition, makes equipment easy to operate and maintain

    由於其本身具有高增益、高輸出功率、低噪聲、帶寬寬、與偏振無關等優點，在很多領域和場合， edfa正逐步取代傳統的光-電-光中繼模式，省去光電/電光轉換的昂貴成本，便於設備的運行維護，成為現代光纖通信系統中不可缺少的關鍵部件。
