Robust Control of Uncertain Systems in Generalized Frequency Domain

In this project, we explore D-decomposition methods applied to control systems with uncertainties. We use a previously developed theory for Generalized Bode Envelopes to find a family of controllers which stabilizes an uncertain system. The approach is similar to classical D-decomposition methods and has been proven to be very useful in the design in the frequency domain. As part of this project, we apply the developed techniques to real-world control systems.
