Queries in control system

  1. Jun 20, 2016 #1
    i have few queries regarding control system in electrical engineering.....
    1)transfer function is defined for linear system ? why is that so....
    2)why transfer function is defined with zero initial condition....why not with initial condition

    A transfer function is the output-to-input signal ratio. Such a ratio can be defined for equal signals forms only.
    (Can you divide a triangle form by a sinus signal?).
    The output signal form is equal to the form of the input signal for linear systems only.
