摘　　要：针对目前主流循环流化床锅炉的主蒸汽温度具有非线性和大惯性特征,随着工况变化会发生动态变化,难以准确建模的问题,笔者基于自抗扰控制理论,对循环流化床锅炉的主蒸汽温度控制方案进行改进,可有效解决当锅炉负荷扰动变化时控制精度差等问题,方案具有较大的应用价值。At present, the main steam temperature of the main circulating fluidized bed boiler has the characteristics of non-linear and large inertia, which will change dynamically with the change of working conditions, so it is difficult to accurately model. Based on the theory of active disturbance rejection control, the authors improve the main steam temperature control scheme of circulating fluidized bed boilerr, which can effectively solve problems such as poor control accuracy when the boiler load disturbance changes, and has great application value.
