  • neural Systems For Control

    If you are acquainted with neural networks, automatic control problems are good industrial applications and have a dynamic or evolutionary nature lacking in static pattern-recognition; control ideas are also prevalent in the study of the natural neural networks found in animals and human beings. If you are interested in the practice and theory of control, artificial neu- ral networks offer a way to synthesize nonlinear controllers, filters, state observers and system identifiers using a parallel method of computation.

    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(yōu)良等優(yōu)點,在中小容量調(diào)速系統(tǒng)和高精度調(diào)速場合發(fā)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(xiàn)象,且其控制系統(tǒng)是一個強非線性、時變和多變量系統(tǒng),要實現(xiàn)高精度調(diào)速就需對其控制策略進行深入研究。 永磁同步電機調(diào)速系統(tǒng)中,位置傳感器的存在使得系統(tǒng)成本增加、結(jié)構(gòu)復(fù)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(jīng)網(wǎng)絡(luò)良好的逼近能力,實現(xiàn)永磁同步電機的無位置傳感器控制。 人工神經(jīng)網(wǎng)絡(luò)(neural Network)可以逼近任意復(fù)雜非線性映射,具有很強的自學(xué)習(xí)自適應(yīng)能力,十分適合于解決復(fù)雜的非線性控制問題。其中,BP神經(jīng)網(wǎng)絡(luò)是目前廣泛應(yīng)用的神經(jīng)網(wǎng)絡(luò)之一,得到了較為深入的研究,其結(jié)構(gòu)簡單,需要離線確定的參數(shù)少、泛化能力強、逼近精度高、實時性強,采用BP神經(jīng)網(wǎng)絡(luò)實現(xiàn)永磁同步電機的調(diào)速控制具有重要意義。 文中提出了基于BP神經(jīng)網(wǎng)絡(luò)的永磁同步電機自適應(yīng)調(diào)速控制策略,建立了一種包含辨識網(wǎng)絡(luò)和控制網(wǎng)絡(luò)的雙神經(jīng)網(wǎng)絡(luò)結(jié)構(gòu)控制系統(tǒng)。辨識網(wǎng)絡(luò)在線動態(tài)辨識系統(tǒng)輸出并對控制網(wǎng)絡(luò)參數(shù)進行調(diào)整,控制網(wǎng)絡(luò)與PI控制方法相結(jié)合實現(xiàn)永磁同步電機自適應(yīng)轉(zhuǎn)速控制。仿真結(jié)果表明,該系統(tǒng)動態(tài)響應(yīng)快、實時性較強、精度較高。 文中提出了一種基于混合訓(xùn)練算法的BP神經(jīng)網(wǎng)絡(luò)永磁同步電機無位置傳感器控制方法。采用混沌優(yōu)化和梯度下降法相結(jié)合的混合算法對BP神經(jīng)網(wǎng)絡(luò)進行離線訓(xùn)練后,將其用于永磁同步電機的轉(zhuǎn)子位置角在線估計。結(jié)果表明,該訓(xùn)練算法可以有效地加快神經(jīng)網(wǎng)絡(luò)收斂速度,且估計的轉(zhuǎn)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(diào)速控制系統(tǒng),并進行了相應(yīng)的軟硬件設(shè)計,為實現(xiàn)永磁同步電機的各種控制策略奠定了實驗基礎(chǔ)。DSP控制系統(tǒng)為神經(jīng)網(wǎng)絡(luò)訓(xùn)練提供樣本,為研究永磁同步電機的自適應(yīng)調(diào)速控制和轉(zhuǎn)子位置角估計創(chuàng)造了條件。
