Abstract
Disclosed is a control system for a variable frequency generator including a main stator winding for providing a generator output, excited by a main rotor winding, and a main exciter rotor winding for energizing the main rotor winding, excited by a main exciter field winding. The control system includes: a plurality of inputs adapted to receive respective signals corresponding to respective generator operating parameters; an output adapted to drive the main exciter field winding; and a plurality of negative feedback loops between the output and the inputs. Each loop includes a respective stability compensation network operable to process a feedback signal corresponding to one of the generator operating parameters.
