Projector Stabilization California University of Pennsylvania Applied Engineering Technology Anthony Abrahamsen Tyler Darabant Royce Riva Tyler Sherry 05/01/2015

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.

The Project Minimize the vibrations. Stabilize the projector.

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