在伺服驅動器速度閉環中，電機轉子實時速度測量精度對于改善速度環 的轉速控制動靜態特性至關重要。為尋求測量精度與系統成本的平衡， 一般采用增量式光電編碼器作為測速傳感器，與其對應的常用測速方法 為M/T測速法。M/T測速法雖然具有一定的測量精度和較寬的測量范圍， 但這種方法有其固有的缺陷，主要包括：1）測速周期內必須檢測到至 少一個完整的碼盤脈沖，限制了最低可測轉速；2）用于測速的2個控制 系統定時器開關難以嚴格保持同步，在速度變化較大的測量場合中無法 保證測速精度。因此應用該測速法的傳統速度環設計方案難以提高伺服 驅動器速度跟隨與控制性能

《人工智能的未來》：詮釋了智能的內涵，闡述了大腦工作的原理， 并告訴我們如何才能制造出真正意義上的智能機器——這樣的智能機器 將不再僅僅是對人類大腦的簡單模仿，它們的智能在許多方面會遠遠 超過人腦。霍金斯認為，從人工智能到神經網絡，早先復制人類智能的 努力無一成功，究其原因，都是由于人們并未真正了解智能的內涵和人 類大腦。所謂智能，就是人腦比較過去、預測未來的能力。大腦不是計 算機，不會亦步亦趨、按部就班的根據輸入產生輸出。
