Variation in settling time with gain

Figures 23.4(a) to (f) show response amplitude at the centre of the composite laminate with time for different gain values for patch B configuration (piezo-patch covering half of the top surface along the clamped side). The plots clearly suggest an exponential drop in settling time with increase in gain value suggesting quick response and faster rate of damping of vibrations.
