Multi-rate sampled-data observers based on a continuous-time design Conference Paper uri icon


  • 2017 IEEE. A multi-rate sampled-data observer for nonlinear systems under asynchronous sampling is developed in this work. The proposed multi-rate observer is based on a continuous-Time design coupled with inter-sample predictors for the sampled measurements. The sampled-data system with the multi-rate observer forms a hybrid system and it is shown that the error dynamics of the overall system is input-To-output stable with respect to measurement errors, by applying the KarafyllisJiang vector small-gain theorem. This sampled-data design also offers robustness with respect to perturbations in the sampling schedule. A numerical example is given to show the effectiveness of the proposed method.
