Two LQ-based MIMO controllers (LQG and LQI
architectures) for lateral inner loop flight control for a large
BlendedWing Body (BWB) passenger aircraft pre-design model
are presented. The main control goals are Dutch roll mode
damping, coordinated turn, and roll response shaping. An open
loop analysis shows that traditional SISO design faces fundamental
limitations, so both controller variants are designed as
MIMO controllers. Their performance is tuned and evaluated,
and their specific properties are discussed and compared. The
controllers are validated on various fuel and payload mass cases
and fulfill all demanded goals. Ongoing and future research
seeks to reduce structural loads and increase passenger comfort
using robust control design methods.
