Robust Partial Authority MPC Architecture in Degraded Visual Environments

Rotorcraft operations in a degraded visual environment, and particularly near the ground or other obstacles, can create a high risk of incident and reduce mission effectiveness. The lack of visual cues can create spatial disorientation and increases pilot workload. In a worst-case scenario the lack of visual cues may lead to spatial disorientation resulting in loss of the aircraft and flight crew. Recent surveys on helicopter survivability indicate that improved flight control laws are a key piece to mitigate aircraft loss and improve flight safety. To this end the Army has requested evaluation of a number of control architecture for the OH-58F Kiowa Warrior. Barron Associates will lead an experienced team to develop and assess modern control law designs within the specifications of the ADS-33E-PRF handling quality requirements. Key to our approach is extensive experience with receding horizon optimal and model predictive controllers and an integrated pilot-controller-vehicle simulation framework that will enable assessment of pilot-vehicle interactions early in the design cycle.
