Near-optimal feedback guidance for an accurate lunar landing
This research presents a novel guidance method for a lunar landing problem. The method facilitates efficiency and autonomy in a landing. The lunar landing problem is posed as a finite-time, fixed-terminal, optimal control problem. As a key finding of this work, the method of solution that is …

Optimal trajectory design under uncertainty
… closed-loop covariance with the inclusion of a feedback guidance law. This covariance shaping technique is applied to reference trajectory design for a generic small reentry vehicle. A baseline trajectory is generated without any robustness considerations, along with an open-loop covariance …

Optimal maneuver guidance with sensor line of sight constraint
The problem of optimal guidance design for the low altitude, subsonic, vertical plane approach maneuver of an air vehicle constrained to maintain view of a fixed final position is studied using a nonlinear, constrained, optimal control problem formulation. Multiple, competing optimization criteria …

Associate-Candidate Relationships: A Study of Teacher Education Field Experiences
… comparative analysis. Participants identified feedback, guidance, support, genuine interactions, and relationship dynamics as central to successful field experiences. Participants also suggested that associate teachers might be better supported in their role if they were offered increased …

New numerical methods for open-loop and feedback solutions to dynamic optimization problems
… approach for synthesizing nearly optimal feedback controllers for optimal control and two-player pursuit-evasion games described by general nonlinear differential equations. A notable revelation from this development is that the resulting control law has an algebraic closed-form structure. …
