Abstract:
In this thesis, the latest human respiratory system is extended such that it addresses the effect of blood acidity on the performance of the human respiratory system. Since the model does not take into account any controller, two PI controllers proposed by Bental have been used to simulate the closed loop behavior of the respiratory system. Since, in the original model blood pH is considered as a constant value, the extended model has been used for the case where the blood pH pumped by heart is assumed to be and the obtained results have been compared with those of the original model. The similarity of the results shows the extended model to be valid for the normal case. Model since t he extended model contains two inputs and three outputs; one should find the appropriate control algorithm to control the outputs of the respiratory system. Various control scenarios have been used to mimic the closed loop behavior of the respiratory system. It has been shown that two control scenario (Ratio control and Cascade control) results in the respiratory system behavior whose qualitative behavior is similar to that of the human respiratory system
