MATLAB/SIMULINK Medical CO2 Insufflator Model with PID-PQT & MPC-PQT Controllers

Abstract

Medical Carbon Dioxide (CO2) insufflator is used in a minimally invasive surgery creating abdominal cavity to provide surgeons with a direct view of internal organs. In our previous work, MATLAB/SIMULINK medical CO2 insufflator has been developed with only abdominal cavity s pressure via a Proportional Integral Derivative (PID) controller. This work permits the simultaneous control of three parameters pressure, flow and temperature through a PID controller. Then, a Model Predictive Controller (MPC) has been implemented to enhance the precision, accuracy, and the response time of the system. The results are promising due to the efficiency of MPC controller in multi-input/multi-output system over PID controller. In the future work, high flow CO2 insufflator will be developed.
