Control of fuel flow to the core gas generator section of the engine is examined including the establishment of non‐dimensional control modes for acceleration, limiting, deceleration limiting and exceedance protection.

    Speed governor response and stability analyses are presented in detail using root locus methods for optimizing governor gain settings.

    Implementation of fuel control modes and fuel pumping and metering concepts are described using specific examples that have been employed in the control of aircraft gas turbines over the past 50 years.

    Both hydro‐mechanical and electronic control designs are presented culminating in the modern FADEC.

    The concept of error budgets is presented as an aid to the prospective fuel control system designer and, finally, qualification and certification considerations are discussed from an installation and environmental perspective.
