Abstract
A method of robust, nonlinear, multi-rate, state estimator design is presented. It can be used to improve robustness in an existing estimator or design a new robust estimator. An expression that can be used to calculate an upper bound on the maximum sampling period and time delay of infrequent measurements, is presented. The upper bound is the latest time at which the next infrequent measurements should arrive to ensure that estimation error does not exceed a desired limit. A binary distillation flash tank is considered to show the application and performance of the estimator
