  2. Hence analysis and design of nonlinear sampled - data systems has been, in recent years, a subject of growing interest in the international community of control research. when a continuous - time plant is controlled using a digitally implemented controller, it is often faced that a continuous - time plant is transformed into its equivalent discrete - time model. a digital controller is usually designed on the base of approximate discrete - time models of the continuous - time nonlinear systems because it is difficult to obtain the closed form of the exact discrete - time model for nonlinear control systems

    利用計算機等一類離散控制裝置來控制連續時間的受控對象時，都會遇到把連續時間系統化為等價的離散時間系統的問題，通過采樣器和保持器來實現離散時間的采樣控制，對于非線性連續受控系統，由於連續系統的時間離散化后一般得不到其等價的精確離散化模型表示的有限形式，實際上由其近似離散化模型代替來設計控制器，而近似會引起信號失真，那麼基於近似離散化模型上設計的采樣控制器，它是否同樣對原連續受控系統有效
  3.

    作者通過歸納總結常規變電站自動化系統的調試方法和維護手段，分析比較了現有的微機保護調試界面，指出了基於pc機的軟體化調試界面的優越性。針對分層分散式變電站自動化系統的特點，提出了利用面向對象編程技術，編制間隔層智能裝置和變電站層監控系統及通訊網路層報文監視的智能化調試軟體的設計思想。該方法可大大簡化變電站自動化系統的調試和維護工作量，進一步縮短變電站自動化系統的安裝調試工期，提高系統運行的安全性與穩定性，具有很大的實用價值。
  5. Finally, some important conclusions were drawn, that is, using distributed pzt transducers, ultrasonic guided waves are generated and received in a pipe. usually, there are many different modes of guided wave propagating in the pipe and these modes are generally dispersive, the specific exciting signal of a harming windowed toneburst with a central frequency of 70khz for decreasing the effect of dispersion was selected. and guided wave are generated using 16 distributed pzt transducers in a circumferential direction for suppressing flexural modes

    首先，對當前本課題研究領域的進展作出綜述，並簡要介紹與超聲導波技術相關的理論基礎；其次，建立了一套有效的實驗裝置，在此實驗裝置基礎上，重點研究了採用分散式pzt傳感器在管中激勵和接收特定模態超聲導波的方法：根據在管狀波導中傳播的超聲波具有頻散現象及多模態特徵，選擇具有單一頻率的特定信號激勵超聲導波，使其頻散最小；同時採用分散式傳感器抑制不同模態的波型。
