Transient response deals with how a system behaves when it moves from one state to another that is usually as a result of change of input from step or impulse type.
This measures the system’s response at the time when the disturbance is applied before the system stabilizes.
With regards to responses and control of electrical, mechanical and other similar systems the transient response is dependant on the dynamics such as natural frequency, damping and time constants.
Key characteristics of transient response include:
Rise time
The time taken for the output of the system from a particular lower percentage value to a higher percentage value of the final value (say 10 to 90 percent).
Overshoot
The deviations of the output of the system in question from its steady-state value.
Settling Time
The period it takes for response of the system to reach and stay at a particular percentage from the final value of response, a percentage that can be a 2% or a 5% for example.
Peak Time
The time it takes for the peak of the response to be reached though through a maximum value.
