We present a new approach for deriving sampled-data observers from continuous-time observers that feature an Input-to-Output Stability property with respect to the output measurement noise and exponential convergence in the noiseless case. The design approach applies to a wide class of systems and yields sampled-data observers that inherit all performance characteristics of the underlying continuous-time observers. The main component of the proposed sampled-data observer is a novel output predictor that encompasses both inter-sample predictors and ZOH-predictors.

关于采样数据观察者的说明

我们提出了一种从连续时间观测器中导出采样数据观测器的新方法，该方法具有输入到输出稳定性，在无噪声情况下具有相对于输出测量噪声和指数收敛的特性。该设计方法适用于范围广泛的系统，产生的采样数据观察器继承了底层连续时间观察器的所有性能特征。所提出的采样数据观察器的主要组成部分是一个新的输出预测器，它包括样本间预测器和 ZOH 预测器。
