| 中文摘要 | 循环流化床锅炉燃烧系统为大滞后、强耦合和非线性的热力系统,其动态特性的复杂性使得目前较多采用的多回路控制系统不能有效地投入自动。通过分析各输入量对各输出量的影响程度和计算各控制回路的相对增益,确立了循环流化床锅炉燃烧系统的多变量控制方案。采用遗传算法对燃烧控制系统进行优化设计,并采用Mento-Carlo方法对控制系统的鲁棒性进行评价。结果表明:基于动态特性的多变量控制系统具有优良的控制性能,该控制系统的鲁棒性能很好。; The combustion system,of circulating fluidized bed boilers,is a thermal system,characterized by time lag,strong coupling and non-linear properties.The complexity of its dynamic behavior makes it impossible for that,at present widely used,multi-loop control system to be effectively put into automatic service.Based on an analysis of the influence,exerted by the input quantities on the output quantities,and after having calculat the relative contribution of each control loop,a multi-variable control version,for the combustion system of circulating fluidized bed boilers,has been decided on;its design optimized by genetic algorithm,and its robustness evaluated by the Monte-Carlo method.Study results indicate that this multi-variable control system,which is based on the dynamic characteristics,is featured by good control properties and satisfactory robustness. |
