Dynamic model of non-linear system

  1. Jun 25, 2016 #1
    i am finding it difficult to get insight about modelling of non linear system (electrical).
    my queries are,
    consider the system is DC DC converter...
    1) I read that to study the dynamics of the system we linearise the non-linear system....why do we want to linearise it?...
    2)can some one please explain me the process of linearisation clearly....why do we want to add perturbation to the operating point...
