open-loop vs closed-loop dc motor speed control

This project focuses on comparing the performance of open-loop and closed-loop speed control systems for a DC motor using MATLAB and Simulin

1. Objective:To model and analyze the difference between open-loop and closed-loop DC motor control systems.
2. Tools Used:

• MATLAB
• Simulink

1. Methodology:

• Develop a transfer function model of a DC motor.
• Simulate open-loop speed control by applying a fixed input voltage.
• Implement a closed-loop control system using a proportional gain (Kp).
• Compare both systems by observing step responses and performance metrics (rise time, settling time, steady-state error).

1. Results:

• Open-loop system is slower and less accurate.
• Closed-loop system achieves faster speed response and stable operation.
• Feedback improves control accuracy significantly.

1. Applications:

• Electric vehicles
• Industrial motor drives
• Robotics and automation systems
