  1. Because there are some shortcomings on tuning the parameters of conventional pid controller, which include the difficulty to make sure the direction of tuning, the possibility to cause the crash of system and the requirement of the system ' s model parameters, a new self - tuning algorithm of pid based on wavelet is proposed in this paper, which is using some wavelet items to describe the state of system through studying the connection between the step response of system and the wavelet transform of the step response and simulating it by use of matlab

    由於常規pid控制器參數調整中存在不少缺陷,如調整方向難以確定,容易引起系統崩潰,有些方法需要知道預先確定系統模參數等。對這些情況,本文通過研究小波換的特點以及控制系統單位階躍響應和響應的小波換之間的關系,在應用hatlab軟體進行了大模擬研究的基礎上,找到了表徵系統狀態的小波標,提出了一種基於小波換的pid參數調整演算法,為研究小波換在控制領域的應用提供了新的思路。
  2. On the basis of the calculating of complexity ( c value ) and combination entropy ( h value ) from the numerical method of geoanomaly analysis, logged signals data ( spontaneous potential, acoustic slowness, spontaneous gamma ray and electrical resistivity ) and seismic data ( amplitude, frequency, phase, etc. ) are processed after regularization of data obtained from linqing basin of shengli oil field. many types of geoanomalies obtained from the computation are analyzed so the spacial variation rules of them can be discovered. then the oil regions can be predicted by this method

    本文創新性地將地質異常概念引入油氣勘探領域,以地質異常理論為導,以勝利油田臨清坳陷油氣地質異常預測研究為例,對我國陸相含油氣盆地的常規測、測試和解釋數據,如與地震相關的數據(振幅、頻率、吸收系數、層速度等) 、與測井相關的數據(然電位、聲波、視電阻率、然伽馬等)等,提取不同數據類的地質異常以及異常組合特徵,通過對這些參數的綜合研究分析其空間化規律,系統地建立有效預測油氣藏的新技術和新方法,進而達到區域油氣資源預測的研究目的。
