Introduction to Gas Turbine Engine Control
In this chapter, an introduction to gas turbine engine operation and control is given. The chapter starts by emphasising engine control in general through a brief survey of conventional control strategies. Engines need to attain high levels of overall efficiency. A number of high-level efficiency criteria are introduced and the use of optimisation within the design cycle is considered. The chapter concludes with a section considering examples of on-line optimisation from a number of different viewpoints to maximise: range at cruise condition, specific fuel consumption and thrust. The aim is to globally optimise the engines overall performance through selection of appropriate control strategies.
