摘　　要：针对火电厂锅炉燃烧过程中主蒸汽压力控制系统的非线性、大时滞和大惯性,辐射能量信号能够对入炉燃料率的变化做出迅速的反映并进行快速补偿,设计一个基于混合灵敏度的H∞控制器作为主控制器。该控制器通过选择合适的加权函数,利用鲁棒控制工具箱得到鲁棒性强的控制器。仿真结果表明该方案显著提高了非线性、大时滞燃烧系统的控制品质。According to the features of nonlinearity,large delay and large inertia of main steam pressure control system of boiler combustion control system,radiation energy signal could make quick reflection for the change of the rate of fuel into the furnace and rapid compensation.A new controller based on the H∞ mixed sensitivity was designed as main controller.By choosing proper weighting function,the MATLAB robust toolbox was used to obtain the H∞ optimal controller.Simulation result shows the project is effective to control nonlinear and large delay system.
