Non-Gaussian Distribution Steering in Nonlinear Dynamics with Conjugate Unscented Transformation
Daniel C. Qi, Kenshiro Oguri, Puneet Singla +1
In highly nonlinear systems such as the ones commonly found in astrodynamics, Gaussian distributions generally evolve into non-Gaussian distributions. This paper introduces a metho…
Convex Bound of Nonlinear Dynamical Errors for Covariance Steering
Daniel C. Qi, Kenshiro Oguri
Applying linear controllers to nonlinear systems requires the dynamical linearization about a reference. In highly nonlinear environments such as cislunar space, the region of vali…
Hands-Off Covariance Steering: Inducing Feedback Sparsity via Iteratively Reweighted Regularization
Naoya Kumagai, Kenshiro Oguri
We consider the problem of optimally steering the state covariance matrix of a discrete-time linear stochastic system to a desired terminal covariance matrix, while inducing the co…
Chance-Constrained Covariance Steering for Discrete-Time Markov Jump Linear Systems
Shaurya Shrivastava, Kenshiro Oguri
In this paper, we solve the chance-constrained covariance steering problem for discrete-time Markov Jump Linear Systems (MJLS) using a convex optimization framework. We derive the…
Pontryagin-Bellman Differential Dynamic Programming for Low-Thrust Trajectory Optimization with Path Constraints
Yanis Sidhoum, Kenshiro Oguri
We present a Differential Dynamic Programming framework that parameterizes the control via Pontryagin's Minimum Principle, for constrained low-thrust trajectory optimization. This…
Robust Cislunar Low-Thrust Trajectory Optimization under Uncertainties via Sequential Covariance Steering
Naoya Kumagai, Kenshiro Oguri
Spacecraft operations are influenced by uncertainties such as dynamics modeling, navigation, and maneuver execution errors. Although mission design has traditionally incorporated h…
Autonomous Horizon-based Asteroid Navigation With Observability-constrained Maneuvers
Aditya Arjun Anibha, Kenshiro Oguri
Small body exploration is a pertinent challenge due to low gravity environments and strong sensitivity to perturbations like Solar Radiation Pressure (SRP). Thus, autonomous method…
