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:

    There is no death! The stars go down
    To rise upon some other shore,
    And bright in heaven’s jewelled crown
    They shine forevermore.
    John Luckey McCreery (1835–1906)

    If the Almighty had intended for you to be rich, he’d have taken care of that a long time ago. The idea of you being rich, that’s plain blasphemy.
    Robert Rossen (1908–1966)

    The general fact is that the most effective way of utilizing human energy is through an organized rivalry, which by specialization and social control is, at the same time, organized co-operation.
    Charles Horton Cooley (1864–1929)
