The Covid-19 pandemic has had a comprehensive and far-reaching impact on various fields, especially in the medical aspect. Additionally, many variants of this coronavirus have appeared due to mutation, each of which has distinguished influences. During the Covid-19 pandemic, medical equipment, especially ventilators, has seen a severe shortage. Thus, many studies of ventilators machine have been carried out around the world. And according to these studies, airflow control is one of the critical issues of ventilator machine research that saves human life. Understanding the above problem, it is necessary to conduct system modeling and obtain a model which has high linearity so that the parameters of the ventilation can be controlled to achieve better accuracy. This paper presents the model identification of a two double-acting piston pump system using experimental data. First order plus dead time method is applied to achieve the identification model. The data used for identification and validation are collected by conducting several practical tests on the two double-acting pistons pump system. The discussion on the identified model and future works are also included in this paper.
