Robust Autopilot Design by Structured H∞ Loop Shaping: An Agile Aerospace Vehicle Application

This study demonstrates an effective systematic control design procedure by applying H∞ Loop-Shaping with a structured controller on an agile aerospace vehicle with a focus on automation. The gain-scheduled implementation is additionally described and tested with non-linear simulations, including a realistic moving point-hit scenario with...

Effect of Lead-Lag Dynamics on Command Filtered Incremental Adaptive Backstepping

The main objective was to analyse the effects of rotor dynamics, and in particular lead-lag and flapping dynamics, on incremental backstepping (IBS). The main focus in this research was on the angular rate controller of a rotorcraft, since it required an idealised rotorcraft model to establish the IBS controller. The idealised rotorcraft model...
