simulation in the induction motor

[haya]

hello,
i would like some help about the simulation of the dynamic(and static also if possible) behavior of the two speed induction motor (the start and especialy the transiton from one speed to an other ).i know
that simulink of matlab resolve such problems well but being no automatic i found dificulties, so if anyone have an exemple already done or know any titorial(simulink)that show such exemples(at the internet sites) i would be grateful.
with regards
