摘    要:传统的多变量系统解耦方法依赖于准确的传递函数和状态空间模型,而很多过程控制对象的准确模型难以获得。本文利用系统辨识所得的一阶CARMA模型构造近似的前馈解耦补偿器,结构简单,计算量少,适宜实时控制使用。当它与在线递推辨识结合使用,则具有自适应动态解耦效果。

关 键 词:多变量系统  解耦  CARMA模型  辨识  降价

Abstract:The classical decoupling method of a multivariable system depends on a strict transfer function or a state space model. However, it is very hard for many process control objects to obtain a strict model. In this paper, a first order CARMA model obtained by system identification is used to construct an approximate feedforward decoupling compensator, which is designed with a simple construction and a small amount of computation and is suitable for real time control. If this decoupling method is combined with an on line recursive identification, an adaptive dynamic decoupling function will be obtained.
Keywords:Multivarianle system  Decoupling  CARMA model  Identification  Reduced order
