  1. Second part - the main contribution and research results of this paper are focused on as follows : ( 1 ) how to use the measurements of a dual frequency gps receiver to determine the ionospheric delay correction model for single frequency gps of a local range ; ( 2 ) how to separate the instrumental biases with the ionospheric delays in gps observation ; ( 3 ) how to establish a large range grid ionosphere model and use the gps data of chinese crust movement observation network to investigate the change law of ionospheric tec of china area ; ( 4 ) how to improve the effectiveness of correcting ionospheric delays for waas ' s users under adverse conditions. ( 5 ) how to establish the basic theory and the corresponding framework of monitoring the stochastic ionospheric disturbance using gps ( 6 ) how to improve the modelling ability of ionospheric delay according to its diurnal, seasonal, annual variations based on gps ; ( 7 ) how to meet the demand of correcting the ionospheric delay of high - precision orbit determination for low - earth satellite using a single frequency gps receiver 1 extracting ( local ) ionospheric information from gps data with high - precision the factors are systematically described and analyzed which limit the precision of using gps data to extract ionospheric delays

    二、具體研究工作的系統報告，主要集中在以下幾方面：研究如何利用單臺雙頻gps接收機的觀測信息確定電離層延遲改正模型，為小范圍的單頻用戶服務；研究如何實時分離gps觀測中的儀器偏差與電離層延遲；研究如何建立較大區域的電離層格網模型，進而初步設想利用中國地殼運動觀測網路深入研究我國領域的電離層的電子濃度變化規律；研究單頻用戶在不利條件下，如何更好地利用電離層延遲改正信息；研究利用gps監測隨機電離層擾動的基本理論和框架方案；研究如何綜合顧及電離層的周日、季節和年變化，進一步提高利用gps模擬電離層延遲的能力；研究如何實現星載單頻gps低軌衛星的精密測軌中的電離層延遲改正要求。
  2. Then one remote supervision system based on virtual instrument technology is studied and realized. the system can measure parameters such as signal level, carrier frequency and snr of remote channel, and can estimate the state of remote channel based on this parameters, and can display the time - domain and frequency - domain wave real time of remote channel, too

    針對目前遠動監控方案的不足，研究並實現了基於虛擬儀器技術的電力遠動通道監控系統，該系統可以對遠動收發信電平、載波頻率和信噪比三個通道參數進行測量，具有實時時域波形和功率譜波形顯示功能，並能根據通道參數對通道狀態進行綜合判斷。
  3. This thesis describes the three important methods for designing pid controller : imc - based method, frequency method and direct synthesis method. we respectively design the pid controllers for the first - order plus dead - time processes, second - order plus dead - time processes, non - minimum phase processes, integrating and unstable processes, then, performance assessment and robustness metrics are used to compare the pid controllers of the individual process

    論文著重研究了pid控制器的三種重要設計方法：內模法、頻域法和直接綜合法，並從確定性性能指標和魯棒性性能指標的角度，比較這些設計方法在一階加純滯后、二階加純滯后、非最小相位、積分和不穩定過程pid控制器設計中的應用效果。
