DC Motor Speed Control Simulation 🚀

This repository contains a Simulink-based simulation project to model and control the speed of a DC motor using classical control techniques such as the PID controller. This project is useful for students and enthusiasts interested in control systems, modeling, and real-time simulation with MATLAB & Simulink.

🧠 Project Objectives

• Model a DC motor using its physical parameters.
• Design and tune a PID controller to maintain desired motor speed.
• Analyze performance (overshoot, settling time, rise time).
• Visualize system response with scopes and plots.
• Demonstrate closed-loop speed regulation under step inputs.

🛠️ Files Included

File/Folder	Description
MyModel.slx	Main Simulink model file
MyModel.slxc	Simulink cache file (auto-generated, ignored going forward)
Machine_Parameters.m	MATLAB script defining motor parameters
DCMotorSpeedControlSimulation.prj	Simulink Project file
resources/project/	Additional model assets or references

Note: You can ignore .slxc — it's an auto-generated Simulink cache file not needed for version control or manual editing.

⚙️ How to Run

1. Clone the repository:

   git clone https://github.com/DhanushGit03/DCMotorSpeedControlSimulation.git

2. Open the .prj file in MATLAB by navigating to the cloned folder using the Open Folder option.

3. Now right-click on the Simulink model and select Model Properties.
4. Navigate to the Call Backs tab, then paste the saved file contents from Machine_Parameters.m into the appropriate callback section (such as InitFcn).
5. Click Apply and then OK.
6. Click the Run button in Simulink to start the simulation.
