1
Q
Percentage Overshoot (%OS)
A
The percentage, with respect to the final response, by which the maximum response exceeds the final respons

Q
Settling time Ts
A
The 2% settling time is the time elapsed when the decaying response reaches and remains within 2% of the final response

Q
Ts is then found as
A
5
Q
Rise time Tr
A
The Rise time can be defined as the time it takes for the response to rise from 10% to 90% of the final value
Difficult to obtain an exact analytical expression for Tr
Tr decreases (i.e. response is faster) with increasing natural frequency
For a given natural frequency, Tr decreases (i.e. response is faster) with decreasing damping ratio
