Recorded in July 2014, Dr. Sanjay discusses the practical challenges of implementing multivariable control (MVC) systems. While the theory of MVC has been around since the 1970s, its application in production systems (circa 2014) remains limited. This lecture provides practical perspectives on control applications, emphasizing the potential value of MVC while stressing the importance of understanding the system's physics to avoid unecessary complexity.
Here, we develop, analyze, and tune a dutch roll damping system with yaw-rate feedback. However, it’s shown that pilot commanded turns can also introduce yaw-rate that is opposed by the dutch roll damper. To deconflict pilot turn and dutch roll damping objectives, a washout filter is introduced. With a brief trade study, a time constant and feedback gain is determined that balances turning and dutch roll damping objectives. The dutch roll damping loop will become an inner loop of a future lesson on angle of side slip control for turn coordination.
