Kim, Hyerim (2015-06-04)Near-future space missions demand the delivery of massive payloads to deep space destinations. Given foreseeable propulsion technology, this is feasible only if we can design trajectories that require the smallest possible ...
-
Prabhu, Kaushik (2023-07-23)Formation flying is a critical technology for future space missions. Distributed estimation architectures will play a key role in achieving multi-spacecraft mission objectives. In the distributed framework, each spacecraft ...

Minimax methods for finding multiple saddle critical points in Banach spaces and their applications Yao, Xudong (Texas A&M University, 2005-11-01)This dissertation was to study computational theory and methods for ?nding multiple saddle critical points in Banach spaces. Two local minimax methods were developed for this purpose. One was for unconstrained cases and ...

Kim, Sung Hyun (2009-05-15)A widespread use of robotic technology in civilian and military applications has generated a need for advanced motion planning algorithms that are real-time implementable. These algorithms are required to navigate autonomous ...
-
Kim, Kyungeun (2013-12-06)The current methods for uncertainty analysis in dynamical systems are restricted in terms of computational cost and evaluation domain since they either use grid points or work only along trajectories. To break through these ...
-
Famularo, Douglas I. (2017-12-07)Hypersonic vehicle research and development has grown recently in the aerospace industry due to the powerful potential of operating a vehicle that flies at substantially higher speeds than typical aircraft. From a guidance, ...
-
Bani Younes, Ahmad H. (2013-08-05)We propose novel methods to utilize orthogonal polynomial approximation in higher dimension spaces, which enable us to modify classical differential equation solvers to perform high precision, long-term orbit propagation. ...
-
Janisch, Brian Scott (2016-07-27)A robust technique for handling parameter and strategy uncertainty in a pursuit-evasion framework is developed. The method is a receding horizon controller valid for problem classes with singularly perturbed trajectories ...
-
Cho, Donghyurn (2013-08-13)Continuous and discrete-time Successive Backward Sweep (SBS) methods for solving nonlinear optimal control problems involving terminal and control constraints are proposed in this dissertation. They closely resemble the ...
