    針對反電動勢類似正弦的準正弦波反電動勢無刷直流電動機，本文提出一種基於六個離散位置信號的自同步svpwm （電壓空間矢量法）控制方法，用以削弱電磁轉矩脈動，分析了實現這種方法的主要控制環節，包括起動時電壓空間矢量的初始定位，阻抗角與電流超前角的合理選擇以及連續轉子位置的估計等。
  2. At first some modification is made in conventional beam forming of frequency domain, namely to estimate doa by arrays outputs on compensated spacial frequency points of echoes. then the cwt is utilized to signal processing in space - frequency domain for estimation of doa, and the corresponding modification is also made. in the dissertation, the computer simulations of doa estimation for both narrow - band and wide - band echoes are given, so do the necessary comparison among several methods and crb

    首先在傳統的頻域波束形成演算法的基礎上，提出對寬帶信號的頻率補償，也即對寬帶回波信號的各空間頻率根據時間頻率的差異進行相應補償，然後對各陣元輸出求和來得到方位估計；其次將連續小波變換引入到空間?頻率處理中，從而完成對目標方位的估計，並進行了相應地補償。
  3. This means the effects can be reduced by long - term continuous observation. but for the short - time observation, for example, the determination of zenith delay, the effects ca n ' t be reduced obviously, because the interval between the zenith delay parameters is often short

    這說明長時間的連續觀測可以削弱海潮的影響，但對于短期的觀測，比如在估計天頂延遲量時，由於估算天頂延遲參數的時間間隔通常較短，海潮的影響還是不能很好地抵消。
  4. The paper also studies fast arithmetic and programming of discrete time quadrature wt and wpt and takes a deep look into their additional applications in motor testing, including denoising, filtering and so on. starting from basic theory of time - frequency analysis and wavelet analysis of asymptotic signals, this paper investigates several if law extraction methods and presents an especially effective one using wavelet ridge
