    論文分別討論了潛器縱向，橫向和航向三個子系統在不同條件下的控制問題，考慮到該潛器潛航時外界干擾主要來自海流，驗證了模糊變結構控制方法對模型參數時變及海流速度、方向變化的強魯棒性，同時將該控制器跟實際工程中常用的pid控制器和常規的變結構控制器的控制效果進行比較，並結合實際情況，將該控制器同縱傾調節相結合進行控制以更好地滿足實際工程的需要。
  2. This thesis defines and classifies the concept of nfr and describe the process measure of some representative nfr. according to subjectivity, relativity and correlation of nfr, we describe nfr using the concept of softgoal and characterize the relation between softgoal with contribution and correlation link, based on the study of goal - oriented requirement analysis

    其次，根據非功能需求的特點，結合當前對面向目標需求分析和建模方法的研究，引入軟目標的概念來描述非功能需求，利用作用關系和相關關系來描述軟目標之間的關系。
  3. Traditional requirement analysis procedure was driven by functional requirements ( fr ), but now people recognize that non - functional requirements ( nfr ) is also important, such as safety and reliability

    傳統的需求工程主要是由功能驅動的，隨著技術發展人們逐漸認識到諸如安全性、可靠性等非功能需求對軟體系統開發成功與否也是非常重要的。
  4. In the method, nfr are explicitly represented as " softgoals " to be " satisficed ". throughout the architectural process, softgoals are incrementally refined, architectural alternatives are considered, design tradeoffs are analyzed, and design decisions are rationalized

    首先，本文給出了非功能需求的定義和詳細分類，以及對非功能需求的相關性進行總結，並採用統一的描述方法重點描述了幾個典型的非功能需求的處理方法。
  5. Last, we utilize the extend mechanism of unified modeling language ( uml ) implement a tool for non - functional requirements requirement analysis and modeling, giving stakeholders one platform for description, elicitation, negotiation and validation of nfr

    最後，為了給需求分析人員和用戶以及軟體設計人員提供一個需求分析的描述、獲取和實現的平臺，我們利用uml的拓展機制描述gonfr的元素，從而實現一個軟體系統分析和建模的工具，以支持對非功能需求的處理過程。
  6. In this thesis, this method interconnect nfr with fr ; on the other hand, fr is judge condition when satisfying nfr. second, in order to fulfill the process of nfr, we using knowledge - based to support the process, avoiding difference on the comprehension among stakeholders and separating analyst from consulting too much literature, so we can help architects achieve nfr during architectural design effectively

    另外，為了更好實現非功能需求的處理過程，我們採用基於知識支持的方法來指導對非功能需求的分析過程，提出了知識提取的幾個規則，使stakeholder之間避免對術語理解的差異，同時避免需求分析人員繁雜的文獻查詢，從而更為有效地幫助有關人員進行非功能需求分析。
  7. This involved some problem of the non - functional requirements of software such as description, elicitation, negotiation and validation. in this thesis we presents a systematic method of goal - oriented non - functional requirements requirement analysis and modeling ( gonfr ) with knowledge - based to help architects achieve nfr during architectural design

    這就涉及到軟體非功能需求的描述、獲取、優化平衡以及驗證等問題。本文提出一個系統的基於知識支持和面向目標建模分析方法gonfr ，該方法用於幫助在體系設計過程中對非功能需求的處理。
