Application of Human-Simulated Intelligent Coordinated Control in Circulating Fluidized Bed Boiler Combustion System

摘要:

针对循环流化床锅炉燃烧系统中主蒸汽压力和床体温度的强耦合问题,提出了基于仿人智能协调控制,并在此基础上与仿人智能模糊控制相结合的解耦控制策略,并将此控制策略应用于燃烧系统进行仿真；仿真结果表明,该策略有效地解决了循环流化床锅炉燃烧系统的非线性、大滞后和强耦合问题,实现了燃烧系统中主蒸汽压力和床体温度的解耦控制,并且在施加扰动后,体现出了一定的抗干扰能力,能收到良好的控制效果。

Abstract:

According to the strong coupling problem between main steam pressure and bed temperature in the combustion system of circulating fluidized bed boiler, we put forward decoupling control strategy based on human-simulated intelligent coordinated control strategy combined with fuzzy control strategy. The simulation of control system applied this control strategy. This method effectively solved the nonlinear, large delay and strong coupling problem in circulating fluidized bed boiler combustion system. Morever, the method realized decoupling control between main steam pressure and bed temperature in the combustion system. It had good anti-interference ability after appling disturbance and achieved good control results.
