Jeonghwan Kim

I'm a Masters student (ECE and Math) in Georgia Tech advised by Dr. Sehoon Ha
I received my Bacheler's degree at Seoul National University, majoring in Electrical and Computer Enginering.
I am interested in robotics control, powered by intersection of reinforcement learning, modern control, and computer animation. I am currently working on fast simulation of quadrupedal robots with trajectory optimization and computer animation.

Projects
Implementation of PPO for Multi-Agent Path Finding with Dynamic Obstacles

Efficient multi-agent path finding algorithm is essential for reducing cost when deploying robots to logoistics warehouses. In this project, we train a Multi Agent variant of Proximal Policy Optimization(PPO) algorithm for multi agent path finding with dynamic obstacles.

Stabilizing Controllers with Root Based Polynomial Regression

We propose a novel method of stabilizing classical controllers via techniques from machine learning. We use Polynomial Root Kernel(PRK) and Polynomial Root Gradients(PRG) to trained neural network to generate both discrete and continuous controllers satisfying root criterion stability. We successfully generated stabilizing feed-back controllers and parallel feed-forward compensator(PFC) along with unique application to Belgian chocolate problem.

Design and Control of Scalable Magnetic Levitation System with Deep Reinforcement Learning

We Model 3DoF levitating magnetic ball with 2D plane of electro magnets on MATLAB/Simulink. The three dimensional positional control of the levitating object was done via Deep Deterministic Policy Gradient (DDPG) algorithm.
