Control of a rocket using gain scheduling

A rocket cannot be controlled using classical control, because of large parameter changes (mass, pressure, ...). Hence, a gain- scheduling control technique is used. This technique consists of designing several controllers for fixed operating points and interpolating between them to construct a global gain-scheduled controller. In this project, a new approach based on linear programming will be used. This approach has the particularity of designing local controllers and interpolating between them in one step.

To achieve this goal, the following steps are proposed:

1. Decouple the MIMO model of the rocket to have several SISO models.
2. Linearize the SISO models around different operating points.
3. Apply the method to design the gain-scheduled controllers.
4. Test the controllers in simulation.
