智能解耦在循环流化床锅炉MIMO控制系统中的应用

Application of Intelligent Decoupling in MIMO Control Systems of Circulating Fluidized Bed Boiler

循环流化床锅炉是多输入多输出(MIMO)系统,是一个多参数、非线性、时变及多变量紧密耦合的复杂系统,很难建立精确的数学模型。采用一般的常规PID解耦控制策略,解耦效果不理想。针对目前流行的智能解耦方案进行了仔细研究,并与常规的解耦控制策略进行比较,致力于提供一种品质良好的CFBB解耦方案。

CFBB is a multiple input and multiple-output （MIMO） system. It is a complex system of multivariable, nonlinear, time variable and tightly coupled. It is difficult to set up a precise mathematical model. The use of general PID decoupling strategy, the result of decoupling is not satisfactory. In this thesis, the popular intelligent decoupling programs were carefully studied, and compared with conventional decoupling strategy. The thesis is committed to providing a good quality of CFBB decoupling program.
