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 rise from error to truth is rare and beautiful.”
    —Victor Hugo (1802–1885)

    “What with making their way and enjoying what they have won, heroes have no time to think. But the sons of heroes—ah, they have all the necessary leisure.”
    —Aldous Huxley (1894–1963)

    “In view of the fact that the number of people living too long has risen catastrophically and still continues to rise.... Question: Must we live as long as modern medicine enables us to?... We control our entry into life, it is time we began to control our exit.”
    —Max Frisch (1911–1991)
