I've got a super-easy book on it if you want to know how to use it quick (will dig it out to get title if you are interested).
-However, if you are into doing a doctorate on it then unfortunately i can't help.
(I once remember working in a power electronics company and had to double pulse a FET in series with R and L, to give a certain peak of current. -I used laplace transforms to correctly select R and L -But this made me the laughing stock of the company -none of the electronics design engineers there ever used Laplace -They just said they did it by trial and error.)
