Rise Time - Rise Time in Control Applications

Rise Time in Control Applications

In control theory, for overdamped systems, rise time is commonly defined as the time for a waveform to go from 10% to 90% of its final value.

The quadratic approximation for normalized rise time for a 2nd-order system, step response, no zeros is:

where ζ is the damping ratio and ω0 is the natural frequency of the network.

However, the proper calculation for rise time from 0 to 100% of an under-damped 2nd-order system is:

where ζ is the damping ratio and ω0 is the natural frequency of the network.

Famous quotes containing the words rise, time and/or control:

    To-morrow I will have finished four-score years. I have lived to rise from the most despised and hated woman in all the world of fifty years ago, until now it seems as if I am loved by you all. If this is true, then I am indeed satisfied.
    Susan B. Anthony (1820–1906)

    It’s true, as Marya Mannes says: “No one believes [a woman’s] time to be sacred. A man at his desk in a room with a closed door is a man at work. A woman at a desk in any room is available.”
    Lillian Breslow Rubin (20th century)

    Not being able to control events, I control myself; and I adapt myself to them, if they do not adapt themselves to me.
    Michel de Montaigne (1533–1592)
