AGUILAR LOPEZ, Ricardo; MARTINEZ GUERRA, Rafael  and  MATA MACHUCA, Juan L.. Temperature Control of Continuous Chemical Reactors Under Noisy Measurements and Model Uncertainties. J. appl. res. technol [online]. 2012, vol.10, n.3, pp.428-446. ISSN 2448-6736.

The aim of this paper is to present the synthesis of a robust control law for the control of a class of nonlinear systems named Liouvillian. The control design is based on a sliding-mode uncertainty estimator developed under the framework of algebraic-differential concepts. The estimation convergence is done by the Lyapunov-type analysis and the closed-loop system stability is shown by means of the regulation error dynamics. Robustness of the proposed control scheme is tested in the face of noise output measurements and model uncertainties. The performance of the proposed control law is illustrated with numerical simulations in which a class of oscillatory chemical system is used as application example.

Keywords : I/O linearizing controller; sliding-mode observer; uncertainty estimation; noisy measurements.
