ABSTRACT:
A regulator for a closed loop control system receives a sinusoidal reference input signal i* and sums it with a feedback signal i to produce an error signal. A control signal is produced by the regulator by combining signal components which include: (a) a component proportional to the error signal; (b) a componet proportional to the integral of the error signal; and (c) a component related to the frequency of the reference input signal. The latter component insures that an accurate control signal is produced by the regulator over a wide frequency range.
