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型參數等。針對這些情況,本文通過研究小波變換的特點以及控制系統單位階躍響應和響應的小波變換之間的關系,在應用hatlab軟體進行了大量模擬研究的基礎上,找到了表徵系統狀態的小波指標,提出了一種基於小波變換的pid參數自調整演算法,為研究小波變換在控制領域的應用提供了新的思路。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,以地質異常理論為指導,以勝利油田臨清坳陷油氣地質異常預測研究為例,針對我國陸相含油氣盆地的常規測量、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(自然電位、聲波、視電阻率、自然伽馬等)等,提取不同數據類型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變化規律,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。
