Abstract

This paper presents a hierarchical control law architecture for future generation rotorcraft for enhanced performance (i.e., handling qualities) and structural durability. The proposed control system has a two-tier hierarchical architecture. The lower-tier is designed using a combination of probabilistic robust control and damage mitigating control methodologies. By allowing different levels of risk under different flight conditions, probabilistic robust control achieves the desired trade off between stability, robustness and nominal performance. Minimization of damage rate is achieved via damage mitigating control, improving health management and durability of the rotorcraft. The upper-tier is designed using discrete-event supervisory control methodology, which monitors the system response for any anomalous behavior, performance degradation and/or potential loss of structural durability. Based on the observed data, the upper-tier supervisor may decide to switch between different modes to satisfy the specified requirements. The system is demonstrated using a high fidelity simulation of the UH-60A helicopter.
