Thanks, Rajasekhar. Hi Rajasekhar, Integrator "wind-up" is a phenomenon which can be seen in control systems which have an integrating controller. Very often, the actuators driven by the controller (electrical,mechanical,...) come to their limits although the integrating controller further integrates. Now, when the the error signal changes its sign (due to the control action) the integrator must be discharged up to a certain degree before the actuator can respond to the new condition. Thus, the integrator has itself wound-up. This leads to a delay within the loop and causes overshoots.
