Control of Respiratory Ventilators Using Boussignac Valve
摘要
The aim of this study was modelling and computer simulation of the ventilator control system in the pressure-controlled ventilation (PCV) model with the use of the Boussignac valve and the construction of a prototype of such a ventilator. The simulation model was based on Matlab/Simulink model of Medical Ventilator with Lung Model. This model is a nonlinear system with a fuzzy Takagi-Sugeno rule base model. A program interface was developed for simulating the operation of ventilator in the PCV mode on-line and to change the mechanical parameters of the lung - resistance and compliance.
