  1.

    由於缺少數據，分析和偏差的復雜性，生命周期評估時常草擬一個界限值（去除所有可能的供應商） ，僅僅停在建立傳播和資源的目錄上，而不是在著手評估和審核的階段
  2. It is not ideal when supposing with pure mathematics to eliminate uncertainty

    運用純數學上的假設來消除不確定性，往往效果不理想。
  3. Because observing patterns to be recognized from multiple sensors can well and truly reflect the features of them, eliminate the uncertainty of the information. pattern recognition methods based on information fusion have already been one of the development trends of pattern recognition field

    從多傳感器視角觀察待識別模式能夠完整準確的反映模式特徵，消除觀察信息的不確定性，因此，基於信息融合的模式識別方法已成為模式識別的發展趨勢之一。
  4. Moreover, the additional knowledge we gain by collecting more information often diminishes - sometimes to the point where marginal gains turn to marginal losses. consider, for instance, the collection of financial - investment information. no amount of knowledge can eliminate the uncertainty and risk inherent in financial investing. also, information overload can result in confusion, which in turn can diminish one ' s ability to assimilate information and apply it usefully. thus, by recognizing the limits of their knowledge, and by accounting for those limits when making decisions, investment advisors can more effectively serve their clients

    在駁論的第一段，作者就舉例子說明知識的有限性並不一定意味著各行各業的人就必須汲取其他方面的知識，恰恰相反，對于醫生、律師或企業家來說意識到了自我知識的有限，並且尋求方法去適應調和這一有限性反而是必要的。
  5. The dissertation refers to comparatively full literatures in the field of vsc, and the development history and characteristics of vsc are summarized, and the elementary concepts, elementary definitions, elementary properties, elementary principles and design methods are particularly introduced, and the causes of the chattering phenomenon are systematically analysed, and the study status of the chattering phenomenon and the main methods to eliminate the chattering are elaborated. for the deficiencies of traditionary methods, three improved methods are developed, which are improved exponent reaching law solution, variable boundary layer solution and the solution by adding an auxiliary continuous control term. for uncertain linear systems, an adaptive fuzzy integral variable structure control stategy ( afivsc ) is put forward to eliminate the chattering around the sliding plane, which introduces fuzzy logic to soften the non - linear discontinuous sig nal in the control variable and utilizes adaptive theory to adjust output membership function according to how much the uncertainty of the system is

    比較全面地查閱了關于變結構控制理論的文獻，總結了滑模變結構控制的發展歷史和特點，詳細介紹了變結構控制的基本概念、基本定義、基本性質、基本原理以及設計方法；系統分析了變結構控制系統抖振產生的機理，並闡述了國內外目前對抖振問題的研究現狀以及消除抖振的主要方法；針對傳統抑制和消除抖振方法的不足，改進了傳統方法，得到了三種新的消除抖振的方法? ?即改進的指數趨近律法、可變邊界層法和附加連續項法；針對不確定性線性系統，在變結構控制策略中引入模糊邏輯和自適應理論來消除滑動平面上的抖振，提出了一種自適應模糊積分變結構控制方案（ afivsc ） ，利用模糊邏輯來柔化控制量中非線性不連續部分，採用自適應理論，根據系統不確定性大小在線調整模糊輸出量的隸屬函數，另外，鑒于模糊控制本質上是有靜差的，所以本文選擇了帶積分項的切換函數，由於積分項的存在使系統較正為無靜差系統。
  6. The second part is a robust compensating controller based on lyapnuov theory which has simple structure and is used for eliminate the effect caused by parametric uncertainty. exact knowledge for robot dynamics is not needed except that the bound of parametric uncertainty must be known

    魯棒補償控制器用於消除參數誤差帶來的不確定性影響，其結構簡單，只需知道系統的一個參數不確定性上界，並保證在系統存在較大的參數誤差情況下，按照對控制器參數的不同選擇，達到3種不同的穩定性結果（即guub 、 gas和ges ） 。
  7. Firstly, considering the uncertainty as full - block matrix whose h norm is bounded, a robust controller is designed and robust stability of the system is analyzed using method. secondly, given the structure information of the uncertainty, synthesis is adopted to design a robust - performance controller to eliminate conserveness in h design. finally, combining the individual advantage of h2 control and h control, a mixed h2 / h optimal controller is designed based on linear matrix inequality which makes the system have good time - domain lqr performance as well as robust stability

    首先，將未建模不確定性看成是范數有界的滿塊矩陣，設計了h _魯棒控制器並用方法分析了系統的魯棒穩定性；其次，考慮未建模不確定性的結構信息，利用綜合設計了魯棒性能控制器，克服了h _控制理論設計時的保守性；最後，結合h _ 2控制和h _控制各自的優勢，基於線性矩陣不等式（ lmi ）設計了h _ 2 h _混合最優控制器，使得系統既具有良好的時域lqr性能又具有較強的魯棒穩定性。
