AB  - In this study, the design of a low cost portable
ventilator with performance analysis have been done to
solve the scarcity of respiratory ventilators for COVID-19
patients. The materials used to build the system are: DC
motor, rotating disc and pneumatic piston. The system
input is the patient heart beat and the output is volume of
air to the patient lung with adjusted breathing rate. This
ventilator adjusts the breathing rate to the patient
depending on his heart beat rate. The performance
analysis of this system have been done using Proportional
Integral Derivative (PID) and Full State Feedback H<sub>2</sub>
controllers. Comparison of the system with the proposed
controllers have been done using a step change and a
random change of the patient heart beat and a promising
result have been analyzed successfully.
