| 摘要 |
A control system for a variable frequency generator of the type comprising a main stator winding (10) for providing a generator output (11), excited by a main rotor winding (9), and a main exciter rotor winding (7) for energising the main rotor winding, excited by a main exciter field winding (5), the control system comprising: a plurality of inputs (30, 31, 32) adapted to receive respective signals corresponding to respective generator operating parameters; an output (5a) adapted to drive the main exciter field winding (5); and a plurality of negative feedback loops (33, 34, 35) between the control system output (5a) and the inputs; each loop including a respective stability compensation network (38, 39, 40) operable to process a feedback signal corresponding to one of said operating parameters. <IMAGE> |
