Overdamped > 1: no overshoot, results in a less sharp response.
Example of a velocity control loop step response with a damping ratio of 2:
A damping ratio higher than 1 may lead to undershoot and non-zero steady state error.
Bandwidth (also called 3 dB bandwidth) is a characteristic of a control loop that characterizes
sharpness of the control loop. It is a frequency the system may follow while keeping 71% of the
amplitude.
Example of velocity control loop 10 Hz sine wave tracking with a requested bandwidth of 10 Hz:
