This paper describes the contribution of a microelectronic fuel control in meeting the demanding requirements of an airborne propulsion turbine engine. Trends in requirements such as control parameters, cost, weight, size and availability are shown. A typical control system is illustrated.
Advantages of digital and analog methods of implementing the computation and logic are given. Manufacturing techniques of the microelectronics are described together with significant contributions of the microelectronic engine control in meeting rapidly stiffening requirements.
