Lyapunov-based Low-thrust Optimal Orbit Transfer: An approach in Cartesian coordinates
Hantian Zhang, Dong Eui Chang, Qingjie Cao
This paper presents a simple approach to low-thrust optimal-fuel and optimal-time transfer problems between two elliptic orbits using the Cartesian coordinates system. In this case…
On the Self-Recovery Phenomenon in the Process of Diffusion
Dong Eui Chang, Soo Jeon
We report a new phenomenon, called self-recovery, in the process of diffusion in a region with boundary. Suppose that a diffusing quantity is uniformly distributed initially and th…
On the Damping-Induced Self-Recovery Phenomenon in Mechanical Systems with Several Unactuated Cyclic Variables
Dong Eui Chang, Soo Jeon
The damping-induced self-recovery phenomenon refers to the fundamental property of underactuated mechanical systems: if an unactuated cyclic variable is under a viscous damping-lik…
On the Method of Interconnection and Damping Assignment Passivity-Based Control for the Stabilization of Mechanical Systems
Dong Eui Chang
Interconnection and damping assignment passivity-based control (IDA-PBC) is an excellent method to stabilize mechanical systems in the Hamiltonian formalism. In this paper, several…
