# 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.

## 🧪 Technologies Used

- **MATLAB** (for scripting and parameter definition)

- **Simulink** (for block diagram-based modeling)

- **Control System Toolbox**

- **PID Controller Tuning**

## ⚙️ How to Run

1. Clone the repository:

   ```bash

   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.
