  • 基于BP神經網絡的永磁同步電機自適應控制研究.rar

    永磁同步電機(Permanent Magnet Synchronous Motor)因功率密度大、效率高、過載能力強、控制性能優良等優點,在中小容量調速系統和高精度調速場合發展迅速。但由于永磁同步電機的磁場具有獨特的交叉耦合和交叉飽和現象,且其控制系統是一個強非線性、時變和多變量系統,要實現高精度調速就需對其控制策略進行深入研究。 永磁同步電機調速系統中,位置傳感器的存在使得系統成本增加、結構復雜、可靠性降低,所以永磁同步電機的無位置傳感器控制成為一個新的研究熱點。本文擬借助于神經網絡良好的逼近能力,實現永磁同步電機的無位置傳感器控制。 人工神經網絡(Neural Network)可以逼近任意復雜非線性映射,具有很強的自學習自適應能力,十分適合于解決復雜的非線性控制問題。其中,BP神經網絡是目前廣泛應用的神經網絡之一,得到了較為深入的研究,其結構簡單,需要離線確定的參數少、泛化能力強、逼近精度高、實時性強,采用BP神經網絡實現永磁同步電機的調速控制具有重要意義。 文中提出了基于BP神經網絡的永磁同步電機自適應調速控制策略,建立了一種包含辨識網絡和控制網絡的雙神經網絡結構控制系統。辨識網絡在線動態辨識系統輸出并對控制網絡參數進行調整,控制網絡與PI控制方法相結合實現永磁同步電機自適應轉速控制。仿真結果表明,該系統動態響應快、實時性較強、精度較高。 文中提出了一種基于混合訓練算法的BP神經網絡永磁同步電機無位置傳感器控制方法。采用混沌優化和梯度下降法相結合的混合算法對BP神經網絡進行離線訓練后,將其用于永磁同步電機的轉子位置角在線估計。結果表明,該訓練算法可以有效地加快神經網絡收斂速度,且估計的轉子位置角誤差較小、精度較高。 文中建立了以TMS320F2812芯片為核心的永磁同步電機調速控制系統,并進行了相應的軟硬件設計,為實現永磁同步電機的各種控制策略奠定了實驗基礎。DSP控制系統為神經網絡訓練提供樣本,為研究永磁同步電機的自適應調速控制和轉子位置角估計創造了條件。

    TION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. WARNING! Although the AD7008 features proprietary ESD protection circuitry, Permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

  • G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion

    G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion to its incidence.Despite a usually good prognosis,GBS is a particularly frightening and often life- altering experience for those diagnosed with the disorder.Many patients are acutely aware of the rapid loss of control of their muscular function, including vital functions such as breathing and swallowing,and fre- quently feel that they are dying.The experience is almost as unnerving for the families of affected individuals.During the acute phase of the ill- ness GBS patients experience the indignity of helplessness in addition to their fear of death or Permanent disability.Prolonged disability is com- mon and some Permanent residual effects are becoming increasingly recognized.It has been our experience in meeting patients at support groups,that individuals who have been affected by GBS have a great desire for a better understanding of the disorder,even years after the acute experience.
