摘要
CFBB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,从而使得单纯用常规的控制理论解决这一自动控制问题变得非常困难。针对CFBB控制难点——汽压—床温耦合系统控制问题,根据其具有强耦合、大迟延、慢时变的特性,采用预测控制和在线辨识自适应控制的方法,致力于实现CFBB的汽压—床温解耦模型的自适应控制。
CFBB is a complex system of multivariable, nonlinear, time variable and tightly coupled. It is hard to build a precise mathematic model and the control problem of such system simply with common control theory is difficult .Aiming at solving the control problem of CFBB, the coupled system of steam pressure and bed temperature, we adopt the method of predict control and adaptive control to realize the adaptive control of such system, according to it＇s characteristic of tightly coupling, long time delaying and slow time variance.
