中文拼音 [qūyúpínggǔ]
趨于平滑
英文
smooth-out-
Massa said drivers will need to be a lot smoother next year, and has warned the lack of traction control is likely to lead to more crashes
馬薩說，下個賽季車手的走線必須更加趨于平滑，並且他還警告說，缺乏牽引力控制系統將會造成更多的碰撞。With limited disturbances considered, sliding mode control is used to design the controller, which ensures the sliding mode to be exponentially converged and the sliding manifold to be reached in limited time from any initial states. and an adaptive law is designed for the unknown inertia matrix
使用魯棒性較強的滑模控制方法設計了控制律：滑動模態是指數收斂的；在有界干擾力矩存在時，任意初始狀態都可以在有限的時間內收斂到滑動平面；對于轉動慣量未知的情形，設計了自適應律，趨近模態是漸近收斂的。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。At present, purchease - sales - inventory manage systems generally have two types of constructive patterns. one is c / s, the other is b / s. in view of their advantages and shortcomings as well as correlative factors, such as its operations characteristic and actuality, being changing intranet environment and customary demanding fashion and developing trend of operations and manage fashions of corporations, the paper puts forward a kind of mixed constructive pattern of c / s and b / s aiming at complex operation, frequent data processing, more data transmitting and high - demand to security, the c / s is used. on the contrary, for those operations of wide scope and low - rise security, the b / s is used. in this way, the mixed patterns has the advantages both c / s and b / s and it satisfied different special demands
目前進銷存系統一般採用c s或b s兩種結構模式，根據圖書進銷存業務特點和現狀、現在企業普遍改造的intranet環境、企業長期的需求習慣方式及將來業務和經營方式的發展趨勢，針對c s 、 b s結構進銷存系統各自優缺點，本文提出了採用一種c s和b s混合結構模式。把業務復雜、數據處理頻繁、數據傳輸量大、安全性要求高的業務，運用c s結構模式，而對于面向范圍廣、安全性要求不高的業務，運用b s結構模式。這樣集c s和b s結構的優點，滿足了圖書進銷存業務不同的特點需求，同時，使企業的原有的經營處理應用系統能平滑過渡，也為滿足今後新的需求具有很好的擴展性。The fuzzy exponential smoothing model has been used for short - term forecasting with a minimum of collected data or unknown system structure to determine a better extrapolative interval in a fuzzy set for an unknown future trend
摘要模糊指數平滑模式對于資料量稀少或系統結構模糊不清之問題，能求解吻合資料未來趨勢的外差模糊預測值，以成功求解未來不確定高的短期預測問題。分享友人
