With the increasing number of COVID-19 cases, the demand of ventilators has increased to such an extent that there is not enough supply of equipment available. For this reason, this research is based on an open source project presented by the Massachusetts Institute of Technology which involves the conditioning of an Artificial Manual Breathing Unit (AMBU bag), that acts as an aid for patients to maintain a constant respiratory cycle. This document presents the calculation of the control matrix for the mechatronic and bio pneumatic systems of the ventilator by implementing a Space-State Model that allows to obtain the control gains that may reduce the error concerning the open loop operation of the ventilator; furthermore, this paper also presents the SIMULINK simulations that demonstrate the efficiency of the calculated control matrixes. Due to these graphic demonstrations, it was observed that the implemented controllers provided an increase in the response time and reduced the error, thus, theoretically, both controllers must provide stability and a higher performance to the ventilator prompting an appropriate assistance to the hospitalized victims of the COVID-19; however, currently, this project is not viable, as it has not been tested in real life and it does not meet the quality and medical requirements for its use in emergencies. |
