High Altitude Balloon Reaction Wheel Stabilization | Seelio
Skip to Main Content

The reaction wheel component of this project was a sub-component of a complete attitude determination and control package for a high altitude balloon payload. The goal of the project was to attempt to stabilize a high altitude balloon payload around its vertical axis when above the jet stream. We went about doing this by building a reaction wheel system sized to be able to handle the perturbations of the atmosphere above the jet stream. Lab results so far are promising. This project is still ongoing.

    This was the model we used for the DC motor current controller.

    This is the first generation reaction wheel we made. It was made up entirely of off the shelf components. The wheel was from an old hardrive

    The second generation system used custom PCB boards and communicated with a Raspberry Pi for receiving torque commands.

    The work I did for this project was broken down into two parts, the dynamics analysis and then embedded programming. Both of these tasks were then broken down into two more parts. For the dynamics you had the dynamics of the payload which could be modeled as a dual spin spacecraft  and the dynamics of the DC motor. Matlab and its Simulink add on were used extensively for this portion of the project. For the embedded programming portion, two embedded systems were actually built to run two controllers, one controlling the current going into the DC motor and another controlling the rotation rate of the payload.
