    在整個飛行包線內，旋翼的推力矢量方向不斷變化，飛機各部件的氣動力隨發動機短艙傾角和空速的變化而變化，因而飛機的飛行動力學有很強的非定常、非線性特性。
  2. The total auto symbol recognition disposition method proposed in this paper can deal with the problem which converts papery of aircraft theory graphics or system graphics into vectorgraphs which can lose some useful information. furthermore, the display technique with multi - level buffer not only resolves the problem of high - speed for aircraft theory graphics or system graphics in cbt, but also ensures scrolling and zooming in / out smoothly and avoids the flashing phenomenon efficiently

    目前紙質的飛機系統圖、原理圖矢量化方法用基本的矢量圖元按其位置來再現原始圖，從而導致矢量后圖中各符號整體信息丟失問題，該文提出的自動符號識別方法可有效地解決該問題，此外改進多級緩沖顯示技術不但可有效地解決cbt中系統圖、飛機原理圖的快速顯示，而且也保證圖形可連續光滑滾動和消除放縮拖動時屏幕閃爍現象。
  3. If everything is either at rest or moving when it occupies a space equal ( to itself ), while the object moved is always in the instant ( in the now ), the moving arrow is unmoved

    （如果每一個物體當它占據與自己相同空間時，不是靜止不動就是在運動中，然而，在一瞬間物體已經運動完成，所以飛矢不動。 ）
  4. Motion control is a comprehensive subject. modern ac drive is a important embranchment in the field of motion control. however, it is difficult to rea1ize high - performance ac drive systems because induction motors are a kind of strongly - coupled nonlinear system with many variables and the torque is not easy to control. with vector control technology decoupling and torque control of ac motor are solved. the basic idea of vector control is that three - phase system is equiva1ent to two - phase system by coordinate transformation and it realizes the decoupling between field current and torque current of the stator in order to control the flux and current respectively, thus induction motor can be considered dc motor and high performance is achieved easily. with the progress of electric and electronic technology and the development of computer, high - integrated special modules and high - precision digital signal processor ( dsp ) are applied to ac drive so that vector control has been developed rapidly

    但是高性能的交流調速系統實現很困難，這是因為交流電機是多變量、強耦合的非線性系統，不易實現高性能轉矩控制。矢量控制技術則解決了交流電機解耦與轉矩控制問題，其基本思路? ?應用坐標變換將三相等效為二相，實現定子勵磁電流分量與轉矩電流分量之間的解耦，達到對交流電機磁鏈與電流分別控制的目的，交流電機等效為直流電機實現高性能調速。隨著電力電子技術的進步，計算機技術飛躍發展，高度集成的專用模塊和高精度的數字信號處理器應用於交流傳動系統中，促進矢量控制迅猛發展，日趨成熟。
  5. The results show that there are no un - receptible responses when the post stall maneuver modes are applied, and agility is raised significantly

    試驗結果表明，使用的4種過失速機動控制模式沒有不可接受的操縱響應，飛機採用推力矢量控制后敏捷性明顯提高。
  6. The results show that the control law can control vectored aircraft to accomplish post - stall maneuvers very well and it is very robust to model uncertainty. 4

    模擬結果表明，該控制律能控制推力矢量飛機順利完成過失速機動，對系統模型的不確定性具有較強的魯棒性。
  7. Here, the aircraft is in extreme flight conditions that is high angles of attack and high angular rates. it can encounter severe nonlinear effects. detailed descriptions of the flight dynamic, aerodynamic models, inverse dynamic and the choice of the control variable are given

    2 、應用經典的微分幾何方法研究了一般的飛行狀態下飛機飛行的控制律，指出不利用矢量推力的飛行系統的控制方程一般都是可以逐步通過動態狀態反饋，適當的坐標變換和正則靜態反饋等三個步驟得以線性化。
