Abstract
A regulating system for direct current motor control having an inner and an outside loop is prevented from winding up in the outside loop, when the inner loop saturates, by a clamping circuit storing the value of the controlling voltage of the outside loop reached at the moment of saturation and generating an overriding error signal by reference to said stored value for providing effective control after saturation has ended.
