Robust Estimation for a CSTR Using a High Order Sliding Mode Observer and an Observer-Based Estimator

[摘要] This paper presents an estimation structure for a continuous stirred-tank reactor, which is comprised ofa sliding mode observer-based estimator coupled with a high-order sliding-mode observer. The wholescheme allows the robust estimation of the state and some parameters, specifically the concentrationof the reactive mass, the heat of reaction and the global coefficient of heat transfer, by measuring thetemperature inside the reactor and the temperature inside the jacket. In order to verify the results, theconvergence proof of the proposed structure is done, and numerical simulations are presented withnoiseless and noisy measurements, suggesting the applicability of the posed approach.
