A Novel Approach for Optimal Trajectory Design with Multiple Operation Modes of Propulsion System, Part 2
Ehsan Taheri, John L. Junkins, Ilya Kolmanovsky +1
Equipping a spacecraft with multiple solar-powered electric engines (of the same or different types) compounds the task of optimal trajectory design due to presence of both real-va…
A Novel Approach for Optimal Trajectory Design with Multiple Operation Modes of Propulsion System, Part 1
Ehsan Taheri, John L. Junkins, Ilya Kolmanovsky +1
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…
An analytical safe approximation to joint chance-constrained programming with additive Gaussian noises
Nan Li, Ilya Kolmanovsky, Anouck Girard
We propose a safe approximation to joint chance-constrained programming where the constraint functions are additively dependent on a normally-distributed random vector. The approxi…
Optimal Strategies for Disjunctive Sensing and Control
Richard L Sutherland, Ilya V Kolmanovsky, Anouck R Girard +2
A disjunctive sensing and actuation problem is considered in which the actuators and sensors are prevented from operating together over any given time step. This problem is motivat…
Attitude Control of a 2U Cubesat by Magnetic and Air Drag Torques
Richard Sutherland, Ilya Kolmanovsky, Anouck Girard
This paper describes the development of a magnetic attitude control subsystem for a 2U cubesat. Due to the presence of gravity gradient torques, the satellite dynamics are open-loo…
Constrained Spacecraft Relative Motion Planning Exploiting Periodic Natural Motion Trajectories and Invariance
Gregory R. Frey, Christopher D. Petersen, Frederick A. Leve +2
Spacecraft relative motion planning is concerned with the design and execution of maneuvers relative to a nominal target. These types of maneuvers are frequently utilized in missio…
