Abstract
A method of controlling power applied to an induction coil assembly used for densifying porous articles with a liquid matrix precursor. The control of applied power addresses dynamic changes in the electrical characteristics of the porous article being densified as it becomes denser. In particular, the power applied is controlled in accordance with changes in resonant frequency of the coupled system of the induction heating system and the porous article.
