2. Outline An outside disturbance is created and shakes the projector.
The inclinometer outputs an analog signal.
The analog signal is fed to the controller to compensate for the disturbance.

3. The Project
Minimize the vibrations.
Stabilize the projector.

4. Raw Data FFT Main harmonics located at 3.2Hz, 6.5Hz, and 9.6Hz
Collected real-time results for simulated model
Frequency

5. System Model

7. Open Loop FFT Simulated harmonics located at 2.5Hz, 6.8Hz, and 9.5Hz
Trial and error to recreate the real-time data
