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 business that we love we rise betime,
    And go to’t with delight.”
    —William Shakespeare (1564–1616)

    “The earth is ready, the time is ripe, for the authoritative expression of the feminine as well as the masculine interpretation of that common social consensus which is slowly writing justice in the State and fraternity in the social order.”
    —Anna Garlin Spencer (1851–1931)

    “When a book, any sort of book, reaches a certain intensity of artistic performance it becomes literature. That intensity may be a matter of style, situation, character, emotional tone, or idea, or half a dozen other things. It may also be a perfection of control over the movement of a story similar to the control a great pitcher has over the ball.”
    —Raymond Chandler (1888–1959)
