結果表明:此次霍山暴雨發生前後,存在明顯的大強度低空急流,並受到中尺度切變線的影響,而且正渦度的加強引起了輻合加劇,提高了上升速度從而引起降水,同時暴雨發生前螺旋度的迅速增強,也為預報提供了根據,另外水汽通量的輻合以及分析位渦反映出的斜壓對流不穩定都充分體現了這次降水的特點。Based on the relationship between the change of the cornea thickness and optical path length, the ablation profile for the correction of wavefront aberration is presented and simulated on computer. the process of scanning - spot excimer laser is studied and simulated on computer. models for calculation of residual wavefront aberration on situations of lateral decentration and torsional misalignment are brought up

文摘:用蓄電池做后備電源的系統(或設備) ,常因過放電導致電池提前報廢而造成設備故障.根據電池電壓隨容量變化的規律,利用電壓比較器和電壓基準源設計製作了電池放電保護電路,當電池放電量接近容量的50 %時,啟動預警信號;當電池放電量達到容量的80 %時,電路自動切斷負載,防止電池過度放電,延長電池壽命,保證系統(或設備)在供電恢復正常后能正常運行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 the same time, this paper summarized the experience on solving the problem of amplitude limitation of the controller output and proposed a method to predict system output by use of the model prediction with feedback correction. the on - line intelligence switch of controller output between the limited amplitude and imc controller output is determined according to the state whether the system output and the predictive output are within the given error range
