An automatic order determination of color isochromatic fringe based on bp artificial neural network is presented 提出基于bp神经网络的彩色域等色线自动定级法。
2.
It solves the problem of model order determination and model validation for multivariable processes . it improves model quality and reduces time for plant test and data analysis and reduces disturbance to unit operation during plant test 它避免了多变量过程辨识方法的模型阶次估计、模型验证的难点；与阶跃测试法相比，采用多通道测试信号，对装置生产的影响小，且允许操作工在测试期间进行操作。
