Detuning the controller is a common workaround which sacrifices performance to ensure stability. Auxiliary feedback loops offer a promising alternative, enabling improved rotor speed regulation without compromising stability. However, while these loops enhance control potential, they also introduce additional dynamic interactions and coupling effects that significantly complicate system behavior. As a result, careful attention must be paid to gain scheduling to avoid adverse interactions and ensure robust performance. Existing gain scheduling strategies for multi-loop systems typically rely on robust stability margins, often neglecting performance-oriented design. This work proposes a novel gain scheduling method based on a linear quadratic regulator that enhances power tracking performance without modifying the existing Reference Open Source COntroller (ROSCO) architecture.
