  1. This thesis is concerned with fault detection and isolation problem for dynamic systems such as norm - bounded uncertain systems, state - delayed uncertain systems, linear parameter - varying systems with time delays, time - delay systems with markovian jump parameters and nonlinear systems by using fault detection filter, threshold selection method and linear matrix inequalities

    本論文研究了動態系統的魯棒故障檢測與分離問題，基於故障檢測濾波器和閾值邏輯方法，採用線性矩陣不等式技術，研究了范數有界不確定系統、時滯不確定系統、時滯lpv系統、時滯馬爾可夫跳躍系統、非線性系統的魯棒故障檢測與分離問題。
  2. First of all, for uncertain systems and state - delayed uncertain systems, the residual generators are constructed based on full - order filters, and the fault detection and isolation problems for these two classes of systems are reduced to h filtering problems by using h control theory. the fault detection filter design is formulated as convex optimization problem subject to lmi constraints in terms of linear matrix inequalities, which can be solved readily by using standard numerical software

    首先，針對非時滯不確定系統和具有狀態時滯的不確定系統，採用全階濾波器構造殘差產生系統，利用h控制理論將這兩類系統的故障檢測與分離問題轉化為h濾波問題，採用線性矩陣不等式技術將魯棒故障檢測濾波器的設計轉化為具有線性矩陣不等式約束的凸優化問題，可利用標準的數學軟體求取。
  3. Spacecrafts are working in the space environment, which is full of sorts of physical mediums. and these mediums will impact on the altitude movement of spacecraft. spacecraft attitude control during propulsive maneuvers is complicated due to several factors as listed below : ( i ) nonlinear dynamics with time delays, ( ii ) modeling and parameter uncertainties, ( iii ) flexible modes due to fuel sloshing and appendages, ( vi ) constraints on propulsive force and torque inputs, ( v ) constraints on acceptable angular rates and attitude, ( iv ) autonomous reconfiguration requirements under failure conditions

    飛行器是在一定的空間環境中飛行，而空間環境中充滿著各種物理介質，對飛行器的姿態運動產生不同程度的影響，所以空間飛行器的姿態控制相當復雜，它受到如下因素的制約： （ ? ）帶時延的非線性動態特性（ ? ）模型和參數的不確定性（ ? ）燃料的激蕩性以及燃料消耗所引起飛行器的質量變化（ ? ）推力和輸入力矩的約束性（ ? ）額定角速度約束和姿態約束（ ? ）在故障發生的情況下自動重新配置的必要性。
  4. It s handy for troubleshooting, problem determination, performance tuning, and more

    對于故障檢修、確定問題和性能調優等非常方便。
  5. Unfortunately, there is a big difference between the vibration of water turbo - generators and other rotating machines. the nature of the coupling arised by hydro -. mechanical and electrical factors, no unique relationship between the specific faults and associated vibration features and additionally the super - imposing of various vibrations at a certain position of a unit make it difficult to ascribe the severity of vibration in accurate words

    然而，水輪發電機組的振動與其他旋轉機械的振動有很大不同，水力、機械、電氣三方面因素引起的振動形成的耦聯、振動故障與振動特徵的非一一對應性及多種振動在某部位的疊加，形成了水輪發電機組振動的復雜性，很難用準確的語言來描述振動的程度及振動是否存在，這就給振動原因的分析帶來一定困難。
  6. Further the backstepping technique is adopted to construct fuzzy robust reconfigurable control scheme for a class of uncertain nonlinear system, which is an integration of fuzzy - mode - based controller and fuzzy adaptive controller. fuzzy adaptive controller in this scheme is used to cancel the effect caused by the modeling error, disturbance, and unknown actuator failures

    進一步，文中針對一類具有不確定性的非線性系統，通過backstepping技術將基於t ? s模糊模型的模糊增益控制器與自適應模糊控制器相結合，提出了一種模糊魯棒重構控制方法，通過模糊自適應控制器的作用，可以自動補償于系統的建模誤差、不確定因素及執行機構故障等造成的影響。
  7. The transient analysis and simulation studies in time - domain showed that the transient capacitance current of busbar is unable to be caught due to the limitation of the given sampling frequency, therefore the transient current singularity of the fault line and the non - fault line will approximate, which prevents to identify the fault line with the criterion calculation result of transient current protection

    研究結果表明，線路出口故障時暫態電流保護完全失去選擇性的根本原因是，在給定的采樣頻率的限制下，難以捕捉到過渡過程中極其短暫的母線分佈電容中的暫態電流，從而故障線路與非故障線路暫態電流波形的奇異性相近，根據故障線路和非故障線路的暫態保護判據計算結果不能正確識別故障線路。
