KPCA主要在图像去噪声方面有应用。此外还可以进行特征提取，降维使用.(KPCA major noise in the image to have the application. You can also feature extraction using dimension reduction.)

分形差值函数是由迭代函数系统IFS实现的，通过离散的数据点构成分形插值函数，证明分形插值函数是这个IFS唯一吸引子。利用MATLAB矩阵运算，实现数据点的分形差值拟合。该算法简介直观。(The fractal difference function is implemented by the IFS fractal interpolation function through the data points of the discrete prove fractal interpolation function only attractor of the IFS. Fractal difference fitting using MATLAB matrix operations, the data points. The algorithms Profile intuitive.)

compensation of dead time effect of the inverter dead time effect causes the impact of the control performance of the INVERTER system, and pointed out that the dead time compensation, the key lies in the current phase of the acquisition, in order to overcome the practical zero of the current ambiguity of the system is proposed based on the two-phase stationary coordinate system under the feedforward dead-time compensation method. by the offset voltage of the three-phase output current cycle Fourier transform is found only compensation 1, 5, 7 harmonic components to eliminate the dead time effect. simulation and experimental results verify the correctness and feasibility of this approach.
