ABSTRACT:
A feedback control loop around a gain element controls the output signal of said gain element responsive to an input or reference signal, and is additionally responsive to a non-linear feedback signal. The feedback loop of this invention comprises computation means for exponentiating a signal representing the output of the gain element to generate said non-linear feedback signal. The control loop of invention provides exceptional transient response when used for driving reactive loads.
