Toward Co-Design of Autonomous Aerospace Cyber-Physical Systems.
(2014)
Modern vehicles are equipped with a complex suite of computing (cyber) and electromechanical (physical) systems. Holistic design, modeling, and optimization of such Cyber-Physical Systems (CPS) requires new techniques ...
Methods for Optimal Output Prediction in Computational Fluid Dynamics.
(2016)
In a Computational Fluid Dynamics (CFD) simulation, not all data is of equal importance. Instead, the goal of the user is often to compute certain critical "outputs" -- such as lift and drag -- accurately. While in recent ...
Resilient Monitoring and Control Systems: Design, Analysis, and Performance Evaluation.
(2015)
Critical infrastructure systems (i.e., power plants, transportation networks, chemical plants, etc.) and their sensor networks are vulnerable to cyber-physical attacks. Cyber-attacks refer to the malicious manipulation of ...
Data-Driven Modeling of Compressible Reacting Flow Using Hardware-Oriented Algorithms
(2022)
High-fidelity numerical simulations of combustion processes in next-generation hypersonic propulsion devices (including, but not limited to, rotating detonation engines and scramjets) play a crucial role in enabling robust ...
UAS Contingency Management Autonomy with Experimentally Validated Models
(2022)
Uncrewed Aerial Systems (UAS) are increasingly deployed for surveillance and transport applications. However, their safety and performance are significant concerns. This dissertation develops a risk-aware autonomy architecture ...
Advances in Game-Theoretic, Set-Theoretic and Optimal Control to Enhance Mobility
(2022)
Advances in mobility technology are expected to greatly improve our access to transportation and the convenience of life. Many challenges in achieving the safety, efficiency, and comfort of mobility systems still exist. ...
Mapping and Real-Time Navigation With Application to Small UAS Urgent Landing
(2021)
Small Unmanned Aircraft Systems (sUAS) operating in low-altitude airspace require flight near buildings and over people. Robust urgent landing capabilities including landing site selection are needed. However, conventional ...
Input and State Estimation for Discrete-Time Linear Systems with Application to Target Tracking and Fault Detection
(2018)
This dissertation first presents a deterministic treatment of discrete-time input reconstruction and state estimation without assuming the existence of a full-rank Markov parameter. Algorithms based on the generalized ...
Large-Scale Simulations of Complex Turbulent Flows: Modulation of Turbulent Boundary Layer Separation and Optimization of Discontinuous Galerkin Methods for Next-Generation HPC Platforms
(2020)
The separation of spatially evolving turbulent boundary layer flow near regions of adverse pressure gradients has been the subject of numerous studies in the context of flow control. Although many studies have demonstrated ...
Metalevel Motion Planning for Unmanned Aircraft Systems: Metrics Definition and Algorithm Selection
(2021)
A diverse suite of manned and unmanned aircraft will occupy future urban airspace. Flight plans must accommodate specific aircraft characteristics, including physical volume with safety zone clearance, landing/takeoff ...
