Abstract
In this paper, the proposed study seeks to augment intuition regarding the role of the adjustment of interest rate in the GDP stabilization, by making use of engineering techniques. It is proposed a macroeconomic analysis by means of a dynamic model, with following use of a control mesh in order to reduce the stabilization time of the system. Different sources of instability are applied to the system in order to evaluate the efficiency of the control mesh. Finally, it is used real data from Brazilian macroeconomy taken from IpeaDATA from the period of 2010 to 2019 to also test the control system.
