本文简单介绍了模型参考自适应系统的三种基本结构:串联,串—并联和并联。用简单例子介绍了三种常用的模型参考自适应系统的基本设计方法,即局部参数优化法,李雅普诺夫函数法和用超稳定性理论设计的方法,最后结合石油化工过程控制的特点介绍了模型参考自适应系统的三个基本应用领域:模型参考自适应控制,参数辨识和状态观测。 This paper briefly introduces three basic structures of model reference adaptive system: series, series-parallel and parallel. The basic design methods of three commonly used model reference adaptive systems are introduced with simple examples, namely the local parameter optimization method, Lyapunov function method and the method of designing with the ultra-stability theory. Finally, according to the characteristics of petrochemical process control Three basic application areas of model reference adaptive system: model reference adaptive control, parameter identification and state observation.
