The objective of this project was to develop a Simulink model of a rudder actuation system and use it to optimize the performance of the system by exploring how different variables have an effect on the system. Triumph is one of the largest aerospace components suppliers for both commercial and military applications. They currently need a control solution for flight surfaces as well as a rudder system for small UAVs. The research and study for this project were conducted through the use of interaction analysis. Anything that negatively affected the system was expected to be found by determining key design parameters, design tolerances, design limits, and manufacturing variances. This model will also be used to optimize the system's performance by tuning damping valves. If successful, the effects of the project will be seen in use for flight surfaces on aircraft including a rudder system.
