Abstract: In described examples of a system having a proportional-integral control module, an error signal is produced that is indicative of a difference between a reference signal and an output signal. An integral control signal is produced by integrating the error signal using an integrator time constant value. During a steady state condition, a first integrator time constant value is used. When an undershoot in the output signal is detected, the integrator time constant value is increased to a second time constant value that is larger than the first integrator time constant value during the undershoot condition. The integrator time constant value is reduced to a third integrator time constant value that is less than the first integrator time constant value during a period following the undershoot condition.
