base2fft
根据DFT的基二分解方法,可以发现在第L(L表示从左到右的运算级数,L=1,2,3…M)级中,每个蝶形的两个输入数据相距B=2^(L-1)个点,同一旋转因子对应着间隔为2^L点的2^(M-L)个蝶形。从输入端开始,逐级进行,共进行M级运算。在进行L级运算时,依次求出个2^(L-1)不同的旋转因子,每求出一个旋转因子,就计算完它对应的所有的2^(M-L)个蝶形。因此我们可以用三重循环程序实现FFT变换。同一级中,每个蝶形的两个输入数据只对本蝶形有用,而且每个蝶形的输入、输出数据节点又同在一条水平线上,所以输出数据可以立即存入原输入数据所占用的存储单元。这种方法可称为原址计算,可节省大量的存储单元。附件包含算法流程图和源程序。(err)

3_110-3
The article concerns observing states of the Induction Motor (IM) using a Luenberger observer in the speed servo drive.
The movement of the motor and observer roots is analyzed for a variable speed. Following the analysis, a new method for
gain evaluation of the IM magnetic flux observer is presented. This structure is extended by including an adaptive speed
observer. The functionality of the presented method is proved in simulations using MATLAB Simulink.
