摘　　要：多模型自适应控制是解决燃料电池发动机电压-电流间的非线性特性导致控制器设计困难的较好方案。本文中提出了一种包含多个线性局域模型的多模型集,其参数通过最小二乘法辨识得到。最后通过仿真数据与实验数据的比较确定模型集包含6个2阶局域模型。验证结果表明模型集有较高的准确性。Multi-model adaptive control is a good scheme for tackling the difficulty in controller design caused by the nonlinear character of the voltage-current relation in fuel cell engine. In this paper a model set covering several linear local models is proposed with its parameters identified by least square technique. Finally a multimodel set consists of six local models of order two is determined through the comparison between simulation and experimental data, and the results of verification show that the model set has a high accuracy.
