ABSTRACT:
An automatic control system includes a multiplier for multiplying the error signal fed to an integrator in accordance with the state of the integrator. The multiplier multiplies the error signal by a unity gain factor over the normal range of integral control; whereas, the multiplier multiplies the error signal by a factor greater than one, typically ten, when the integrator output is saturated at either the minimum or maximum values. The high multiplication value of the error signal ensures a sufficiently quick recovery from an integrator saturation condition.
