Comparative Analysis of Airflow Regulation in Ventilator Systems Using Various Control Strategies

Dhiyaa Sheltag Shanan,
Saleem Khalefa Kadhim

Abstract: Ventilator designs, pivotal in providing respiratory support to patients, often grapple with performance optimization challenges due to variable patient conditions and intricate mechanical components. This research strives to identify the optimal control strategy that can assure maximal patient safety and efficient ventilator operation. We compared three control strategies: the conventional Proportional-Integral-Derivative (PID) control, the Nonlinear PID control, and the sliding mode control (SMC) equipped wi… Show more

“…There are two phases that can be found in the SMC strategy: the reaching phase and the sliding phase. The perturbations will be compensated and rejected during the sliding phase [34][35][36]. However, during the reaching phase, disturbances and model uncertainties affect the system.…”

“…The mechanical ventilation device, comprising an electrically powered blower unit, generates the requisite pressure for patient lung inflation (Po) via a hose medium. Mathematical models have been instrumental in resolving complex engineering challenges [11,12] and are similarly utilized to elucidate lung mechanics and enhance mechanical ventilation therapy [13]. A prevalent approach in existing literature involves the use of a single-compartment lung model, accounting for lung elastance (inverse of compliance) and airway resistance [14].…”
