基于神经网络的交叉耦合控制技术研究

his paper researches on the contour error control technology based on a XY platform of CNC machines driven by linear motors, and designs a neural network cross-coupling controller (NN-CCC). On the basis of cross-coupling control (CCC), the theory of neural network (NN) is analyzed. The neural network PID (NN-PID) controller is designed by combining NN with PID control, which is applied to the single-axis controller and cross-coupling controller. A simulation model of NN-CCC is built in MATLAB. It is shown in experiments that the NN-CCC controller reduces the contour error of the system effectively, and the ability of self-learning, adaptive.
