  1. First, in virtual of identification of flaws is a typical of in - verse problems, proceeding from time - harmonic electromagnetic maxwell ' s equa - tion and helmholtz equation, the uniqueness and existence of direct scattering problems including the numerical algorithms of diverse of boundary conditions is given. second, the uniqueness and existence of inverse scattering problems and the theory of ill - posed integral equation are briefly looked back upon. finally, indicator function method for boundary identification is set up under all kinds of boundary conditions for inverse scattering of homogenous and inhomogenous objects, meanwhile, the proof of possibility for near - field measurements and nu - merical simulation are given

    由於缺陷的識別是一類典型的反問題,因而首先從時電磁maxwell方程helmholz方程出發,具地闡述了求解正散射問題的有關方法,包括各種(夾雜)邊界條件下的值解法,就解的存在性唯一性給予了肯定的回答;隨后對逆散射問題的理論作了簡短的回顧,包括解的唯一性以及非線性不適定積分方程的處理等;然後對均勻介質非均勻介質的逆散射問題建了在各種邊界條件下的邊界識別的指示方法,鑒于近場據獲得的重要性,對近場測試時邊界識別的方法給予了相應的證明,並且實現了值模擬。
  2. In the last, the modern control theory and simulink in matlab have been integrated together, and it has been applied in active control of the platform structure elastically supported ; a mechanical model and an equation of motion in state space have been established. based on coc, dynamic response of the platform structure elastically supported has been studied under simple harmonic load ; the influence of different values of weight function to the active control efficiency of the structure has also been discussed

    本文還將現代控制理論與matlab的simulink動態模擬軟包相結合,將其應用於彈性支承平臺結構的主動控制中;建了彈性支承平臺結構主動控制理論的力學模型狀態空間內的運動方程;應用經典線性最優控制演算法對彈性支承平臺結構在簡荷載作用下的動力響應進行閉環控制;分別從理論值計算兩個方面討論了狀態權矩陣q控制權矩陣r的不同取值對控制效果的影響。
