模糊PID控制在循环流化床锅炉燃烧系统中的设计及仿真

Design and Simulation of Fuzzy PID Control in CirculatingFluidized Bed Boiler Combustion System

基于循环流化床锅炉(CFBB)燃烧系统非线性、多变量、大时滞等特点,提出采用模糊PID控制方案对循环流化床锅炉燃烧系统进行优化控制,并与常规PID控制器进行仿真对比.结果表明,模糊PID控制器的控制效果较常规PID要好.

Based on the characteristics of circulating fluidized bed boiler(CFBB)combustion system,such as nonlinearity,multivariable and large time delay,this paper proposed a fuzzy PID control scheme to optimize the combustion system of CFBB,and compares it with PID controller.The results showed that the control effect of fuzzy PID controller is better than that of conventional PID controller.
