have led to the development of new promising concept for the safe and efficient operation of …

Solutions to practical optimal control problems (OCPs) may consist of control profiles that
switch between control limits or assume values interior to their admissible set, either due to …

The development of self-propelled particles at the micro-and the nanoscale has sparked a
huge potential for future applications in active matter physics, microsurgery, and targeted …

This review paper attempts to provide a useful reference for space habitat designs that
advance the ability of humans to live in space for long periods of time. Five space habitat …

Application of indirect optimization methods to solve constrained optimal control problems is
not a straightforward task. This study presents a new construct, the Uniform …

Efficient performance of a number of engineering systems is achieved through different
modes of operation-yielding systems described as “hybrid”, containing both real-valued and …

In the preliminary interplanetary mission design stage, a fast low-thrust (LT) transfer cost
approximator will improve the mission design efficiency and enable us to design more …

Closed-loop feedback-driven control laws can be used to solve low-thrust many-revolution
trajectory design and guidance problems with minimal computational cost. Lyapunov-based …
