A Proximal Method for Composite Optimization with Smooth and Convex Components
Samet Uzun, Dayou Luo, Behçet Açıkmeşe +1
We introduce prox-convex for minimizing , where and are convex, and are smooth, and each component of is convex (possibly nonsmooth).…
Continuous-time Constrained Funnel Synthesis for Incrementally Quadratic Nonlinear Systems
Taewan Kim, Dayou Luo, Behçet Açıkmeşe
This paper presents a convex optimization-based framework for synthesizing time-varying controlled invariant funnels and associated feedback control around a given nominal trajecto…
Onboard Dual Quaternion Guidance for Rocket Landing
Abhinav G. Kamath, Javier A. Doll, Purnanand Elango +8
The dual quaternion guidance (DQG) algorithm was selected as the candidate 6-DoF powered-descent guidance algorithm for NASA's Safe and Precise Landing -- Integrated Capabilities E…
Successive Convexification for Passively-Safe Spacecraft Rendezvous on Near Rectilinear Halo Orbit
Purnanand Elango, Abraham P. Vinod, Kenji Kitamura +3
We present an optimization-based approach for fuel-efficient spacecraft rendezvous to the Gateway, a space station that will be deployed on a near rectilinear halo orbit (NRHO) aro…
Newton-PIPG: A Fast Hybrid Algorithm for Quadratic Programs in Optimal Control
Dayou Luo, Yue Yu, Maryam Fazel +1
We propose Newton-PIPG, an efficient method for solving quadratic programming (QP) problems arising in optimal control, subject to additional set constraints. Newton-PIPG integrate…
Impulsive Relative Motion Control with Continuous-Time Constraint Satisfaction for Cislunar Space Missions
Fabio Spada, Purnanand Elango, Behçet Açıkmeşe
Recent investments in cislunar applications open new frontiers for space missions within highly nonlinear dynamical regimes. In this paper, we propose a method based on Sequential…
