| 中文摘要 |
| 针对非线性系统模型参数辨识问题, 提出了一种简化E:Coli觅食优化算法, 该算法是基于大肠杆菌(E.Coli)的化学趋向性行为, 包含翻转算子和游动算子, 同时还采用个体历史最佳位置和群体最佳位置对E:Coli群体进行更新(优值跟踪算子). 以重油热解三集总非线性模型参数估计验证了简化E:Coli 觅食优化算法的效果, 实验结果表明了简化E:Coli觅食优化算法的有效性, 为非线性系统模型参数估计提供了一种新方法. |
| 英文摘要 |
| A simplified E:Coli foraging optimization algorithm based on the chemotactic behavior of E:Coli is presented in this paper for the parameter estimation problem of nonlinear system model (NSM). The simplified E:Coli algorithm includes a tumbling operator, a swimming operator, the optimal position of individual E:Coli and the location of all E.Coli swarm are adopted to update the locations of swarm (tracing operator of optimal values). The effectiveness of the proposed simplified E:Coli foraging optimization algorithm is demonstrated by simulation experiments on the parameter estimation of the NSM for heavy oil thermal cracking. The results show that the simplified E:Coli model is valid and provides an attractive method to the estimation of parameters of NSM. |
