MORALES-DIAZ, A.; VAZQUEZ-SANDOVAL, A.D.  e  CARLOS-HERNANDEZ, S.. Analysis and control of a distributed parameter reactor for pyrolysis of wood. Rev. Mex. Ing. Quím [online]. 2015, vol.14, n.2, pp.543-552. ISSN 1665-2738.

This document introduces a methodology for the design of a Proportional Integral + Sliding Mode Control (PI+SM) and its application to a biomass pyrolysis process. The objective of the proposed controller is to promote the transformation of wood into gaseous products, which have high energy value. First, a distributed parameter model of a pyrolysis reactor (from specialized literature) isanalyzed and modified in order to lie implemented in Matlab. After that, a based sliding mode controller is developed considering the reactor temperature as the controlled variable and the applied heat as the control input. Different scenarios are considered and the performance of the designed controller is compared with a classical PI controller and the proces s open loop behavtor via numerical simulation. The results show that the proposed control strategy enhances the gaseous components in the process output.
