本文研究了输出采样慢、输入更新率快的多速率采样系统的控制器设计问题。为了设计具有快速输入更新周期的输出反馈控制器，提出了一种基于被控系统降阶fi一阶模型的自适应输出估值器。所提出的自适应输出估值器是针对被控系统的降阶fi一阶模型而设计的，因此与普通的自适应观测器相比具有相对简单的结构。本文的结果在一个实验液位过程系统上得到了验证。
This paper deals with the problem of designing a controller for multirate sampled systems with slow output sampling and fast input updating rates. An adaptive output estimator based on a reduced first order model of the controlled system will be proposed in order to design an output feedback controller with a fast-rate input updating period. The proposed adaptive output estimator is designed for a reduced first order model of the controlled system and so has relatively simple structure compared with common adaptive observers. The results reported here are validated on an experimental liquid level process system.
