Robust Navigation for Racing Drones based on Imitation Learning and Modularization
Tianqi Wang, Dong Eui Chang
This paper presents a vision-based modularized drone racing navigation system that uses a customized convolutional neural network (CNN) for the perception module to produce high-le…
The Adaptive Dynamic Programming Toolbox
Xiaowei Xing, Dong Eui Chang
The paper develops the Adaptive Dynamic Programming Toolbox (ADPT), which solves optimal control problems for continuous-time nonlinear systems. Based on the adaptive dynamic progr…
Tracking Controller Design for Satellite Attitude Under Unknown Constant Disturbance Using Stable Embedding
Wonshick Ko, Karmvir Singh Phogat, Nicolas Petit +1
We propose a tracking control law for the fully actuated rigid body system in the presence of any unknown constant disturbance by employing quaternions with the stable embedding te…
Double Prioritized State Recycled Experience Replay
Fanchen Bu, Dong Eui Chang
Experience replay enables online reinforcement learning agents to store and reuse the previous experiences of interacting with the environment. In the original method, the experien…
Invariant extended Kalman filter on matrix Lie groups
Karmvir Singh Phogat, Dong Eui Chang
We derive symmetry preserving invariant extended Kalman filters (IEKF) on matrix Lie groups. These Kalman filters have an advantage over conventional extended Kalman filters as the…
Model Predictive Tracking Control for Invariant Systems on Matrix Lie Groups via Stable Embedding into Euclidean Spaces
Dong Eui Chang, Karmvir Singh Phogat, Jongeun Choi
For controller design for systems on manifolds embedded in Euclidean space, it is convenient to utilize a theory that requires a single global coordinate system on the ambient Eucl…
