Square Root-Factorized Covariance Steering
Naoya Kumagai, Kenshiro Oguri
Covariance steering (CS) synthesizes a control policy which drives the state's mean and covariance matrix towards desired values. Offering tractable computation of a closed-loop po…
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…
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…
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…
Robust Controller Synthesis under Markovian Mode Switching with Periodic LTV Dynamics
Shaurya Shrivastava, Kenshiro Oguri
In this work, we propose novel LMI-based controller synthesis frameworks for periodically time-varying Markov-jump linear systems. We first discuss the necessary conditions for mea…
