Sistema de controle de uma incubadora neonatal segundo a norma NBR IEC 60.601-2/19: aspectos de avaliação, identificação dinâmica e novas propostas

Abstract

In this work was built a system of hardware and software engaged in a commercial incubator turning it into a platform to study the process of humidity and temperature characteristic of this system. Using the software on a computer can make measurements of controlled variables and modify the values of the manipulated variables, in this case the resistor heating the air in the temperature’s system and the heating resistor of the water in the humidity’s system. Process models were identified and a predictive controller type GPC is designed to meet the criteria defined in the standard NBR IEC 60601-2/19. To verify compliance with the criteria by the controller was built a system of hardware and software to perform some of the tests required by the standard. The performance of the controller was designed compared to the controller pre-existing commercial incubator. It was verified that the controller designed could meet the criteria of the standard more efficiently than the already pre existing business in the incubator.
