研究了具有快速均匀输入更新速率和缓慢非均匀输出采样速率的非均匀采样多速率系统的自适应输出反馈控制设计问题。针对非均匀采样系统，提出了一种采用自适应输出估计器的输入更新速率快速采样周期下的快速率自适应输出反馈控制设计方案。所提出的自适应输出反馈控制是通过只使用慢速率采样的测量输出和快速速率更新的输入来设计的。根据被控系统的ASPR特性，简要分析了所得到的快速率输出反馈控制系统的稳定性。
This paper deals with an adaptive output feedback control design problem for non-uniformly sampled multirate systems with a fast uniform input updating rate and slow non-uniform output sampling rates. A design scheme of a fast-rate adaptive output feedback control at the fast sampling period of the input updating rate will be proposed for non-uniformly sampled systems using an adaptive output estimator. The proposed adaptive output feedback control is designed by using only measured outputs of slow rate samplings and fast rate updating input. We also analyze the stability of the obtained fast rate output feedback control system briefly based on ASPR properties of the controlled system.
