Abstract
The present control circuit and method extends the operating range of digitally sampled control loops. A programmable output of a generator is controlled. The programmable output includes a an output level having a corresponding set point. The generator has a drive input that is driven to an actual drive point for controlling the output level of the programmable output. A set point corresponding to a requested output level is determined. A predicted drive point is then determined. The actual drive point of the generator drive input is forced to the predicted drive point. The output level of the programmable output is sensed. A digital output signal that is representative of the sensed output level is generated. The actual drive point of the generator drive input is controlled based on the digital output signal, such that the output level of the programmable output is controlled. The actual drive point corresponding to the requested output level is then stored.
