Respiratory Rate Control System using MATLAB and Simulink

Overview

This project models a closed-loop respiratory rate control system using MATLAB and Simulink. A first-order respiratory plant is controlled using P, PI, and PID controllers to analyze system performance and compare their responses.

Features

• Closed-loop respiratory control model
• P, PI, and PID controller implementation
• Step response analysis
• Controller performance comparison
• MATLAB and Simulink implementation

Tools Used

• MATLAB R2025b
• Simulink
• Control System Toolbox
