The quadruped robot has to assess the feasibility of upcoming terrains before making contact to safely traverse various environments. This assessment is called traversability in the literature on quadruped robots. Trasversability has recently posed c

The perception of a quadruped robot is crucial in determining how the robot has to move while crossing challenging terrains. However, robustness in the quadruped perception is still a dilemma when facing a slippery, deformable, and reflective terrain

In hybrid AC/DC microgrids, a bidirectional interlink converter (IC) connecting the AC subgrid and DC subgrid is controlled to manage proper power sharing between both subgrids. This study proposes the design scheme of a model-based IC controller for

In contrast with traditional control input design techniques based on mathematical models of the system, in data-driven control approaches, which have recently gained substantial attention, the controller is derived directly from the data that are co

Due to the intrinsic intermittent nature of renewable energy source, their utility in a microgrid can be enhanced by adding an energy storage system (ESS). Using a lookup table type MPC (Model Predictive Control), this study presents an optimal charg

Reinforcement learning (RL) trains an agent by maximizing the sum of a discounted reward. Since the discount factor has a critical effect on the learning performance of the RL agent, it is important to choose the discount factor properly. When uncert

This paper proposes a scheduling method of dual ESSs (Energy Storage Systems) for the purpose of reducing the peak load when there are sudden loads or generation changes during the on-peak time. The first ESS is scheduled once a day based on a day-ah

Abstract Pure Ti or Ti alloys are recently spot-lighted in construction industries because they have excellent resistance to corrosions, chemicals, and climates as well as various coloring characteristics, but their wide applications are postponed by
