This report provides an overview of essential aspects of mechanical ventilation systems, including their operational principles and the mathematical modeling of Brushless DC motors. It specifically emphasizes the utilization of a variable-speed BLDC motor to drive a blower, allowing for the generation of adjustable air pressure levels through the use of a Pulse Width Modulation (PWM) signal to control the supplied voltage. Consequently, this directly influences the motor's speed, which is proportionate to the output pressure. Additionally, a PID controller is employed to attain the optimum required pressure level while minimizing deviations. In this research work, various tools and software are employed, including a designated motor driver and air pressure or flow sensors. These components are utilized to establish a mathematical relationship between input power and output pressure, enabling the implementation of an effective control process for this application.
