  1. As a non - linear and multi - coupled system, the control of the ac induction motor ( acim ) has long been challenging. thanks to the vector control algorithm, acim can offer the same control capabilities and dynamic performance as traditional high - performance dc motors. with the vector control algorithm, the stator current of acim can be expressed in two orthogonal axes, and thus the rotor flux part and torque are de - coupled

    交流感應電機難于控制是因為它是一個非線性、多耦合的系統，矢量控制演算法通過坐標變換將異步電機的定子電流分解為轉子磁鏈方向和與之垂直方向的兩個分量分別進行控制，從而實現轉子磁通和轉矩的解耦，使得交流感應電機的動態性能可以和直流電機媲美。
  2. 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。
  3. In chapter 3, the non - linear equation was linearized with the jacobi matrix, and then the linearized equation was transformed into fixed frame to analyze the stability problem with eigenvalue method ( on - ground or hovering ) or floquet theory ( forward flight ). meanwhile, the equation was perturbed by sweep frequency excitation from steady state to get transit decay of lag response which was then transformed into fixed frame with a numerical fourier coordination transformation ( fct ). the fixed frame response along with the body response was analyzed via an fft to determine modal frequencies

    然後，在穩態響應的基礎上利用雅各比矩陣對非線性方程進行了線化，線化后的方程利用多槳葉坐標變換轉換到固定系下后，利用直接特徵值分析（地面、懸停）或floquet理論（前飛）對系統進行了穩定性分析;同時，對系統進行了瞬態響應分析;在系統達到穩態的基礎上進行掃頻激勵，用fft變換求得系統頻率，進而用移動矩形窗方法分析得到系統的阻尼。
  4. Changing operations on the fly ? converting, say, a calculation of a matrix of numbers to a parallel - processing computation ? requires the relatively slow rewiring of connections between large blocks of transistors, not the individual elements ( gates ) that perform a processor ' s logic operations

    若要以動態的方式改變操作（例如將數字矩陣的計算轉換為平行計算） ，得將大區塊電晶體間的連結緩慢地重新接線，而非直接改變處理器里執行邏輯運算的個別元件（邏輯閘） 。
  5. Because the method uses the linear measurable function of bearings varying with time, so it is more effective than the normal method which based on bearings of the target directly, and at the same time it can overcome the limits when use the normal method in special situation

    由於該方法將目標方位隨時間變化的非線性關系轉換到另一空間的線性關系，這使得檢測更加有效、直觀，並且能夠克服直接採用方位序列檢測目標轉向機動在特殊情況下失效的限制。
  6. The last, taking into account of the nonlinear transformation from sphere frame to cartesian frame, maneuvering target tracking is simulated by using current statistical model and converted measurement kalman filter ( cmkf ) without linearization bias in the statistical condition. the paper presents the converted measurement covariance that determines when to use the current measurements vs. the predicted state, and the simulation results are satisfied

    最後，針對球坐標系與直角坐標系之間的變換是非線性變換的特點，哈爾濱工程大學博士學位論文運用統計條件下不存在線性化誤差的轉換測量卡爾曼濾波演算法，結合「當前」機動模型對機動目標進行了模擬研究。
  7. The synoptic scale system kinetic energy could not be converted directly to the subsynoptic scale system kinetic energy, which was accomplished by the nonlinear interaction of different scale systems

    天氣尺度動能向次天氣尺度動能轉換，但天氣尺度動能和次天氣尺度動能不能直接進行轉換，而必須通過不同尺度之間的非線性相互作用來實現。
  8.
