Modeling and Simulation of a Bacteriological Incubator

Resumo

Bacteriological incubator consists of equipment that provides an optimized environment for the development of bacteria, frequently used for the development and testing of antibiotics and antiseptics. This work aims to perform white box modeling and simulation of a bacteriological incubator with an operating range of up to 50 °C, presenting a comparison of the P (Proportional), PI (Proportional-Integral) and PD (Proportional-Derivative) compensators in the process loop, enunciating the advantages and disadvantages. Furthermore, the simulation was developed in the MATLAB/Simulink environment, using as reference the commercial bacteriological incubator BF115, manufactured by BINDER. As a result, for the heating process, the PI compensator meets the design requirements and it was verified in computer simulation, while the others, even for cooling, do not meet these requirements and they are not implementable.
