Safety is a critical concern when applying reinforcement learning (RL) to real-world control tasks. However, existing safe RL works either only consider expected safety constraint violations and fail ...

In this article, a variable gain super-twisting algorithm based on a barrier function is proposed for a class of first order disturbed systems with uncertain control coefficient and whose disturbances ...

The blade tip speed limit of a propeller plane's propeller can determine the plane's top speed for reasons relating to design ...

Some may already be familiar with the sonic boom that accompanies a break to the sound barrier, but when and why would ...
