Robust H∞ Control Design Parameter Optimization via Genetic Algorithm for Lateral Control of a BWB type Aircraft *

This work presents a comprehensive, optimization-based robust control design approach: utilizing DK-iteration control synthesis and closed-loop evaluation via goal attainment, a genetic algorithm optimizes this design-and-validation process in its free design parameters. This method is applied to a lateral flight control design task for a flexible, large Blended Wing Body (BWB) aircraft configuration. Control goals include time-domain rigid-body response specifications and loads alleviation objectives. First optimization results yield a robust controller that, although not fulfilling all posed goals yet, strongly reduces structure loads compared to an initial design.
