As the bases of the proposed transform coefficients are very close, the transform normalization can be implemented only on the encoder side and the dequantization table size can be reduced compared with the transform used in h. 264 mpeg - 4 avc. along with the feature of the proposed transform, adaptive dead - zone quantization optimization for the proposed transform is studied
Dct變換具有很好的能量集中特性，並且實現簡單，早已被廣泛地應用到各種類型的編碼標準中，如mpeg - 1 ， mpeg - 2 ， mpeg - 4 ， h . 263等，但浮點dct變換由於浮點舍入精度的問題會產生編解碼失配。 -
Abstract : a microprocessor - based adaptive voltage instantaneous trip protection is proposed and analysed. the voltage setting can be automatically online calculated and determined according to current operation condition of power system and the protection zone is enlarged. as a result, the adaptive voltage instantaneous trip protection is more superior than the same conventional ones
文摘:為了克服傳統電壓速斷保護的動作性能受運行方式變化影響的缺點，提出了利用在線實時計算系統電源側綜合阻抗的方法實現微機式自適應電壓速斷保護，分析結果表明它比傳統的電壓速斷保護有著非常明顯的優越性。 -
Usually we linearize them approximately in industrial process, but in some cases this ca n ' t satisfy the request of automatic control which makes us consider the nonlinear factors in the industrial process. in practical process of power plants the typical structure nonlinear case is dead - zone and the latter case is the nonlinear variance of objects ' parametres with the changes of working condition. the nonlinear research is parallel with the linearity and adaptive method can be used to deal with nonlinear cases. in this paper two adaptive control methods are used to solve the problems brought by the dead - zone of boiler negative pressure system and the nonlinear changes of the milling system ' s character parameters, which achieved good results
在生產中通常對非線性作近似線性化處理；但在某些情況下線性近似達不到自動控制的要求，必須對生產過程中的非線性情況進行考慮。在火電廠的實際生產中，典型的結構非線性之一是死區；參數非線性多發生在控制對象特性隨工況變化而變化，表徵其特徵參數變化呈非線性。非線性控制的研究與線性控制的研究是并行的，針對非線性情況，可以採用自適應的控制方法。
