One question on modeling and control?

is the transient response same as impluse response?One question on modeling and control?
Not exactly the same:





A transient response or natural response is the response of a system to a change from equilibrium. Specifically, transient response in Mechanical Engineering is the portion of the response that approaches zero after a sufficiently long time (i.e., as t approaches infinity). (Contrast with steady-state response). Examples:


1. In a mechanical system a simple example is a mass/spring/damper system. The transient response is the position of the mass x(t) as the system returns to equilibrium after an initial force or a non zero initial condition.


2. n electrical engineering a simple example would be the output of a 5 volt DC power supply when it is turned on: the transient response is from the time the switch is flipped until the output reaches a steady 5 volts. At this time the power supply reaches its steady-state response of a constant 5 volts.





The impulse response and step response are transient responses to a specific input (an impulse and a step, respectively) in a mechanical or electrical system.
