进行逐步线性回归，借鉴了主成分分析算法（PCA），IMC-PID是利用内模控制原理来对PID参数进行计算，代码里有很完整的注释和解释，采用加权网络中节点强度和权重都是幂率分布的模型，基于负熵最大的独立分量分析，采用偏最小二乘法。- Stepwise linear regression, It draws on principal component analysis algorithm (PCA), The IMC- PID is using the internal model control principle for PID parameters is calculated, Code, there are very complete notes and explanations Using weighted model nodes in the network strength and weight are power law distribution, Based on negative entropy largest independent component analysis, Partial least squares method.
