  1. The wavelet multi - analysis is adopted to further understand the microstructure of solids holdup fluctuation, the vivid fingermark images show that it is a fractal and dissipative structure. the low and frequency signals reflect the dilute phase fluctuation behavior and dense phase ( cluster ) fluctuation behavior, respectively. to deep understand the multi - scales characteristic of gas - solids circulating fluidization, the wp decompose methods for obtaining the eigenvalue of gas - solid fluidized bed has been developed. the results show that eigenvalues of different scales are effective for identification of non - uniform and dynamic structure of gas - solid fluidized bed

    多分辨分析法得到指圖形象地揭示了顆粒濃度的自相似、分叉等具有混沌特徵的微觀結構;小分解后信號中的低頻和高頻成分分別代表了稀相和密相的行為,小包分解提取能量特徵值的方法能夠揭示氣固的多尺度特性,不同尺度上的能量特徵值四川大學碩十論文反映了氣固循環流化系統中存在的非均勻態時空結構。
  2. 3. with fourier decomposition, the main component of pulsating torque, torque ripple is studied. it can be determined that torque ripple is caused by harmonic order 6n under the usual common conditions

    3 、對造成轉矩的主要成分轉矩進行諧分析,得出在一般假設情況下,無刷直流電機系統的轉矩由電磁轉矩的6n次諧造成的結論。
  3. 8. a pulsating torque minimization approach based on disturbance observer is proposed. the new disturbance observer is designed to observe the unknown torque disturbance caused by the torque ripple, the varying of the motor parameters, the changing of load torque and the not ideal performance of the inverter

    該系統將負載轉矩、轉矩以及由電機參數的變化引起的轉矩干擾作為系統干擾,用干擾觀測器進行觀測,以此為基礎對轉矩進行補償,實現對轉矩的抑制。
  4. A permanent magnet synchronous motor is selected so that the system could work excellently. multiform measures are taken to weakening the torque ripple, such as adopting stator - flume, choosing right ratio of magnet - width and slot - width, and programming properly. a permanent magnet synchronous motor cad software is worked out for predigesting the design of the motor

    力矩是衡量交流伺服系統性能優劣的重要指標,為達到理想的控制效果,系統採用正弦的稀土永磁同步電機作為執行元件,電機本體的設計綜合採用定子斜槽、將轉子永磁體連續移位、合理選擇永磁體寬度和齒槽寬度比等方法,基本消除了齒槽轉矩;對于轉矩,系統採用軟體的方式加以削弱和補償。
