你會得到大驚喜!!

本書的作者有長達10年的控製工程技術工作經曆，加之非常明確的編著目的——培養學生掌握閉環控製係統構建、控製器設計、係統現場調試等方麵的技術與方法，使本書具有理論聯係實際、工程背景強的基本特色和鮮明特點。

1.總體結構獨特，突齣工程實踐；

全書正文由五部分組成，思路開闊，內容由淺入深，層次分明，係統性強。第一部分“引論”共四章，占全書除附錄外的23.3%篇幅，這在其他同類書籍中較為少見，有利於初學者對自動控製的概念、閉環係統的基本組成與常用部件、係統類型、控製的目的與評價標準等有一個全麵、清晰的認識。

2.內容融閤多門課程，結閤技術標準；

本書以閉環控製係統的分析、設計為主綫，涉及的被控對象包括電係統、氣動係統、液壓係統、熱力係統、機械係統等，將自動控製理論、自動檢測技術、自動檢測技術、電機氣動基礎、電力電子技術、過程控製係統、運動控製係統、電氣控製與PLC等多門課程融閤在一起，形成一個有機的整體。

3.論述深度把握閤理，采用啓發性方式敘述；

書中每章前都列齣該章學習目的和需要重點掌握的內容，便於讀者目標明確地學習，並自我衡量是否達到本章學習要求。全書的16章中有14章都引論。引論的內容起到如下幾個作用：①概括全章的內容；②承上啓下，提齣問題，以便在此後的各節中逐一解決；③闡明重要要領。

4.插圖強調聯係實際，習題側重工程訓練。

全書的插圖經過精心設計，直觀、清晰，有助於概念的理解。書中有相當數量的工程圖，如氣動控製閥的機械結構圖、工業傳送帶控製係統電氣控製原理圖等等，體現瞭與工程緊密聯係的特點。一插圖配有較大篇幅的文明說明，一方麵方便瞭讀者，另一一方麵使正文的文字簡練。
