Title: Electronic speed control for gas turbine - has error correction circuit with variable amplifier having inverse engine transfer gain
Inventor: BARBOT ANDRE MAURICE
IPC: H02P23/00
Filed: 1974-08-30
Abstract: The engine (1) is fitted with a speed sensing device and transmits a signal (N) to a difference detector which compares the signal (N) with the value (NO) set by the throttle control (13).
