  For more than 20 years, the Korteweg-de Vries equation has been intensively
explored from the mathematical point of view. Regarding control theory, when
adding an internal force term in this equation, it is well known that the
Korteweg-de Vries equation is exponentially stable in a bounded domain. In this
work, we propose a weak forcing mechanism, with a lower cost than that already
existing in the literature, to achieve the result of the global exponential
stability to the Korteweg-de Vries equation.
