Abstract:In this paper, the extreme learning machine (ELM) was improved based on strange nonchaotic optimization (SNO) and used to solve the coupling problem of cross-direction (CD) basis weight system. Firstly, the SNO based on a piecewise logistic map was used to optimize the randomly generated weights and thresholds between the input layer and the hidden layer, which solved the disadvantage of insufficient optimization for ELM. Then, SNO extreme leaming machine (SNOELM) decouplers were designed to decouple the multivariable system. Finally, it was compared with the improved extreme learning machine, whale optimization extreme learning machine (WOELM) and particle swarm optimization extreme leaming machine (PSOELM). Simulation results demonstrated that the SNOELM decoupling method had better optimization ability than ELM and had higher decoupling accuracy and faster decoupling speed than WOELM and PSOELM. |
