Closed-Loop Model-Based Control Barrier Functions with Application to Robust Flight Envelope Protection
Johannes Autenrieb, Mark Spiller, Peter A. Fisher +3
Ensuring operation of aerospace systems within prescribed flight envelope limits is a fundamental requirement for modern flight control architectures. Flight envelope protection ai…
Flight Envelope Protection for a Hypersonic Glide Vehicle Using Adaptive Safety-Critical Control
Johannes Autenrieb, Peter A. Fisher, Anuradha Annaswamy
This paper presents an adaptive safety-critical control framework for flight envelope protection (FEP) of hypersonic glide vehicles (HGVs) under model uncertainty. The proposed arc…
Robust Safety Filters for Lipschitz-Bounded Adaptive Closed-Loop Systems with Structured Uncertainties
Johannes Autenrieb, Peter A. Fisher, Anuradha Annaswamy
Adaptive control provides closed-loop stability and reference tracking for uncertain dynamical systems through online parameter adaptation. These properties alone, however, do not…
Auction-Based Responsibility Allocation for Scalable Decentralized Safety Filters in Cooperative Multi-Agent Collision Avoidance
Johannes Autenrieb, Mark Spiller
This paper proposes a scalable decentralized safety filter for multi-agent systems based on high-order control barrier functions (HOCBFs) and auction-based responsibility allocatio…
Control Allocation Algorithm for Hypersonic Glide Vehicles with Input Limitations
Johannes Autenrieb, Patrick Gruhn
Hypersonic glide vehicles (HGVs) operate in challenging flight regimes characterized by strong nonlinearities in actuation and stringent physical constraints. These include state-d…
Decentralized CBF-based Safety Filters for Collision Avoidance of Cooperative Missile Systems with Input Constraints
Johannes Autenrieb, Mark Spiller
This paper presents a decentralized safety filter for collision avoidance in multi-agent aerospace interception scenarios. The approach leverages robust control barrier functions (…
