Description: 算法介绍
矩阵求逆在程序中很常见,主要应用于求Billboard矩阵。按照定义的计算方法乘法运算,严重影响了性能。在需要大量Billboard矩阵运算时,矩阵求逆的优化能极大提高性能。这里要介绍的矩阵求逆算法称为全选主元高斯-约旦法。
高斯-约旦法(全选主元)求逆的步骤如下:
首先,对于 k 从 0 到 n - 1 作如下几步:
从第 k 行、第 k 列开始的右下角子阵中选取绝对值最大的元素,并记住次元素所在的行号和列号,在通过行交换和列交换将它交换到主元素位置上。这一步称为全选主元。
m(k, k) = 1 / m(k, k)
m(k, j) = m(k, j) * m(k, k),j = 0, 1, ..., n-1;j != k
m(i, j) = m(i, j) - m(i, k) * m(k, j),i, j = 0, 1, ..., n-1;i, j != k
m(i, k) = -m(i, k) * m(k, k),i = 0, 1, ..., n-1;i != k
最后,根据在全选主元过程中所记录的行、列交换的信息进行恢复,恢复的原则如下:在全选主元过程中,先交换的行(列)后进行恢复;原来的行(列)交换用列(行)交换来恢复。-algorithm introduced in the matrix inversion process is very common, which are mainly used for Billboard matrix. In accordance with the definition of the method of calculating multiplication, seriously affecting the performance. The need for a large number of Billboard matrix operations, matrix inversion optimization can significantly improve performance. Here we introduce the matrix inversion algorithm called full-elected PCA Gauss-Jordan and France. Gauss-Jordan and France (all elected PCA) inversion of the following steps : First, for k from 0 to n-1 for the following steps : from the first trip k, k started out the bottom right corner Subarray largest absolute selected elements, and element remember meeting the line and out, the adoption OK exchange and the exchange out of its exchange

Description: Introducing the rank-weight method into the
basic ant colony optimization (ACO), we use the modified
ACO to optimize the weights and thresholds value of neural
networks (NN). And when the BPNN is being trained, this
method can solve the disadvantages of running into the
minimum easily, and enhance the convergence speed. So we get
a heuristic method, which is good at time efficiency and
derivation efficiency that is ACOrw-BP. Then this method was
used to identify the speed of the motor in direct toque control
(DTC).The results of the simulation showed that: the modified
ACOrw-BP neural network not only has the ability of mapping
widely, but also enhancing the operation efficiency obviously.
The speed of the motor can be identified accurately by this
method, and the result is good. So, it implements the direct
toque control of speed sensorless.
