在我们以前的工作中，我们开发了一种基于Luenberger观测器设计与样本间预测器耦合的异步采样线性系统多速率观测器设计方法。在这篇文章中，多速率多延迟观测器的设计问题是解决异步采样和可能的测量延迟占。该观测器在两个连续延迟测量之间的时间间隔内采用了一种可用的多速率观测器设计。一个死区补偿方法的开发，以补偿延迟的影响，并更新过去的估计时，延迟的测量到达。多速率观测器的稳定性和鲁棒性将保持在非常数，任意大的测量延迟。一个数学例子和气相聚乙烯反应器的例子证明了所提出的观测器在非均匀采样和非恒定测量延迟的存在下具有良好的性能。© 2018美国化学工程师学会AIChE J，65：562-570，2019
In our previous work, we developed a multirate observer design method in linear systems with asynchronous sampling based on a Luenberger observer design coupled with inter‐sample predictors. In this article, the problem of multirate multidelay observer design is addressed where both asynchronous sampling and possible measurement delays are accounted for. The proposed observer adopts an available multirate observer design in the time interval between two consecutive delayed measurements. A dead time compensation approach is developed to compensate for the effect of delay and update past estimates when a delayed measurement arrives. The stability and robustness properties of the multirate observer will be preserved under nonconstant, arbitrarily large measurement delays. A mathematical example and a gas‐phase polyethylene reactor example demonstrate good performance of the proposed observer in the presence of nonuniform sampling and nonconstant measurement delays. © 2018 American Institute of Chemical EngineersAIChE J, 65: 562–570, 2019
