PCA算法程序 pca
PCA算法程序设计步骤：
1、去均值
2、计算协方差矩阵及其特征值和特征向量
3、计算协方差矩阵的特征值大于阈值的个数
4、降序排列特征值
5、去掉较小的特征值
6、去掉较大的特征值(一般没有这一步）
7、合并选择的特征值
8、选择相应的特征值和特征向量
9、计算白化矩阵
10、提取主分量
(PCA algorithm programming steps: 1 to mean 2, calculation of covariance matrix and its eigenvalues and eigenvectors 3, the calculation of covariance matrix eigenvalues greater than the threshold number of 4, in descending order of eigenvalue 5, remove the smaller eigenvalue 6, remove the larger eigenvalue (usually not this step) 7, the combined choice of eigenvalues 8, select the appropriate eigenvalues and eigenvectors 9, computing whitening matrix 10, principal component extraction)

说明： 采用D-H法建立了多自由度机械臂末端执行器相对于基础坐标系的位置与姿态，即多自由度机械臂的正运动学模型。其次对多自由度机械臂的逆运动学模型进行了分析。最后通过采用Langrange法对多自由度机械臂的动力学进行了建模，并对多自由度机械臂的动力学模型及其特点进行了分析。 针对多自由度机械臂数学模型的不确定性问题，提出一种基于RBF神经网络的机械臂自适应控制方法。(The position and attitude of the end effector of the multi DOF Manipulator relative to the basic coordinate system is established by using the D-H method, that is, the forward kinematics model of the multi DOF Manipulator. Secondly, the inverse kinematics model of multi DOF Manipulator is analyzed. In the end, the dynamics model of the multi degree of freedom manipulator is established by using the Langrange method, and the dynamics model and characteristics of the multi degree of freedom manipulator are analyzed. Aiming at the uncertainty of the mathematical model of the multi degree of freedom manipulator, an adaptive control method based on RBF neural network is proposed.)
