Development and Validation of a Civil Aircraft Engine Simulation Model for Advanced Controller Design

Abstract: This thesis is concerned with the results of a joint academic and industrial study on the development of a detailed nonlinear dynamic model of a turbofan jet engine to be used for research into advanced control strategies for civil turbofan aircraft engines. The model is representative of a dual shaft engine with variable bleed, variable stator vanes, turbine cooling, heat transfer, and a duct and exhaust nozzle. A switched, gain-scheduled, feedback control system incorporating bumpless transfer and antiwindup… Show more

“…In fact, it is well-known that the aerothermal component-level models can capture the engine dynamics very accurately [7][8][9][10][11][12]. However the component-level models are not control-oriented due to the fact the key components such as fan, compressor, and turbine are represented by lookup tables or some other non-analytical modules such as (C or Fortran) program codes, while (unfortunately) most of the control theories assume that an analytical model exists before control design.…”

“…Because of this, Integral Wind-Up Protection (IWUP) is used to reduce the effect of the integral term of the controller. An approach to IWUP from [13,5] was adopted for our control problem. The main idea with this approach is to decrease the error seen by the integrators.…”

“…According to Suraweera (17) , component level modelling (CLM) plays a fundamental role in engine modelling. It has largely been used to model engine outputs (17)(18)(19)(20)(21)(22)(23) , performance deterioration (24) and fault diagnosis (25) . This CLM approach consists in modelling each engine component based on thermodynamical assumptions and equations (26) .…”
