📌 Project Overview

The goal of this project is to simulate and analyze the behavior of a servo motor system under different conditions. Two versions of the model are provided:

✅ Basic Servo Motor Simulation (ServoMotor.slx)
✅ Enhanced Version with Controller & Subsystems (CreatingTestScenariosandComparingSimulations_2.slx)

Additionally, a Large vs. Small Disturbance Analysis was conducted to examine system response under varying input conditions.

📊 Large vs. Small Disturbance Analysis

This project compares the servo motor's behavior under different disturbance magnitudes to evaluate control system robustness.

🔹 Key Findings:

• Small Disturbance → System remains stable with minor deviations.
• Large Disturbance → System experiences oscillations but recovers due to controller action.

📈 Disturbance Rejection Techniques:

✅ PID Controller Tuning
✅ System Response Monitoring
✅ Performance Evaluation
