摘　　要：由于锅炉的燃烧控制系统是一个具有强耦合性的较复杂的多变量非线性控制系统,现有的控制方法不能达到较理想的控制效果,还造成了资源的浪费。针对这种情况,提出了双重启发式动态规划(DHP)控制方法,通过对DHP原理的分析和锅炉燃烧控制系统的研究,结合神经网络建立数学模型,将DHP方法应用于锅炉燃烧控制系统中,最后根据控制要求进行仿真。结果显示系统的各个状态量均能够被稳定控制在合理的范围内,并且系统反应迅速,达到了理想的控制效果,证明了DHP方法的适用性。Boiler combustion control system is a complex multivariable nonlinear system with strong coupling,the existing control methods can not chieve ideal control effect,which causes the waste of resources. In view of this situation,a control method of Dual Heuristic Dynamic Programming（DHP） was proposed,based on the analysis of the principle of DHP and the study of boiler combustion control system,and combined with neural network,we established a mathematical model. The method of DHP was applied in boiler combustion control system and the simulation experiment was carried out according to the control requirement at last. The results show that each state of the system can be controled in a reasonable range steadily,and the system responses quickly. The feasibility of the DHP method was proved.
