LOPEZ PEREZ, Pablo A.  and  AGUILAR-LOPEZ, Ricardo. Dynamic nonlinear feedback for temperature control of continuous stirred reactor with complex behavior. J. appl. res. technol [online]. 2009, vol.7, n.2, pp.202-217. ISSN 2448-6736.

The main objective of this work is to present an alternative methodology for the design of a class of integral high order sliding-mode controller applied to a class of continuous chemical reactor with complex behavior for temperature tracking purposes. The proposed design is based on the differential geometry framework, where the named reaching trajectory contains a high order sliding mode term in order to diminish chattering. Considering that the proposed technique is model based, an observer-based uncertainty estimator is coupled, which provides robustness against model uncertainties and noisy measurements. Numerical simulations are performed in order to show the capacities of the proposed controller, which is compared with other nonlinear methodologies.

Keywords : Chemical Reactor; Temperature tracking; observer based high order sliding mode controller; robust performance.
