Constrained Fuel and Time Optimal 6DOF Powered Descent Guidance Using Indirect Optimization
Nicholas P. Nurre, Ehsan Taheri
Powered descent guidance (PDG) problems subject to six-degrees-of-freedom (6DOF) dynamics allow for enforcement of practical attitude constraints. However, numerical solutions to 6…

Expanding the Class of Quadratic Control-Lyapunov Functions for Low-Thrust Trajectory Optimization
Nicholas P. Nurre, Saeid Tafazzol, Ehsan Taheri
Control laws derived from Control-Lyapunov Functions (CLFs) offer an efficient way for generating near-optimal many-revolution low-thrust trajectories. A common approach to constru…
