# Controllability study of some selected chemical reactions

OData: XML JSON What's this?The aim of controlling chemical reactions is to maximize the amount of the target product and to minimize the amount of the by-products. In order to achieve this control objective we must know the conditions of controllability for given reactions and choices of input variables.

In my thesis I deal with controllability, specially with strong reachability of chemical reactions. The input is choosen as the change of the temperature. The dynamic of the reactions are nonlinear. In my analysis I determine the dimension of the Lie-algebra which is generated by the input vector fields and the vector fields of the system. Using this Lie-algebra I give conditions for controllability of the reactions. First, I determine the conditions for strong reachability in case of oximation reaction in acidic and in basic medium also. Then I give sufficient condition for systems contain reversible reaction step.

In the second part of the thesis I study motion planning of reactions. In my analysis I determine how we can plan input besides given motion in case of systems with special structures (serial reactions, parallel reactions and one step reactions).

Finally I present the simulation of the cloosed loop control in Matlab-Simulink.
