【摘要】 循环流化床锅炉作为一个分布参数、非线性、时变、多变量耦合对象,很难建立起精确的数学模型,常规的PID控制方案效果不理想。介绍一种基于神经网络模型的模糊预测控制,运用该方法对循环流化床锅炉主气温进行控制,应用MAT-LAB7.1进行仿真,结果表明具工程实用价值。更多还原

【Abstract】 It is difficult to build up a precise mathematical model for the circulating fluidized bed (CFBB) boiler,because the CFBB is an object with distributed parameter,nonlinear ,time-vary and multivariable coupling.The effect of routine PID control method is not ideal.So this paper constitutes a general model of the controlled object based on the fuzzy predictive control method by combining the predictive control and fuzzy control.The simulation by MATLAB7.1.更多还原
