Recursive Partial Least Squares and Its Applications

GONG Pei-wen,LI Chun-fu,GE Ming(School of Automation,Hangzhou Dianzi University,Hangzhou Zhejiang 310018,China)  
In this paper,recursive partial least squares(RPLS) algorithm is proposed.This algorithm uses forgetting factor method to be weighted old parameter matrices,and combines with new data matrix,thus input and output data matrix is constituted,and then gets model by using PLS method.Combining with actual industrial process requirements,the steps of this algorithm are proposed,and the paper uses the algorithm to establish coal gasifier syngas component concentration of soft-sensor model.Results show that recursive partial least squares algorithm can effectively update the model,make the model adapt to the changes of the process,and also can improve the prediction performance.
