摘　　要：针对火电厂燃烧控制系统传统控制策略的不足,给出了以辐射能信号为串级控制的中间被调量的H∞鲁棒控制燃烧系统。介绍了设计控制器的过程,通过仿真分析了该控制器的稳定性和鲁棒性,并与采用参数自调整的辐射能信号的模糊PI复合控制系统进行了比较。仿真结果显示:该控制器有良好的鲁棒控制稳定性和鲁棒控制性能。To overcome the weakness of traditional control strategy for combustion system in power plant,this paper proposes a design of H∞ robust controller which takes the radiant energy as the intermediate variation of cascade control.The procedure of the controller design is presented.The stability and robustness of the controller are analyzed by simulation.Finally,the designed controller is compared with the fuzzy PI controller which is based on self-turning for radiant energy.Simulation results show that the designed controller has good robust stability and robust performance.
