Abstract

The objective of the F100 multivariable controls program was to demonstrate modern control design methodology applied to a state-of-the-art aircraft turbine over its entire flight envelope. Linear quadratic regulator design methods were used to develop feedback gains for a series of operating points. Reference schedules were used to translate pilot and ambient inputs to reference point specifications. A transient controller produced smooth and rapid transitions from one operating point to another. A variable structure integral trim system produced specified steady-state performance and limit accommodation in the presence of simulated degradation effects and instrument errors. The resulting control logic was extensively tested on a hybrid simulation of the F100 turbofan and will be used to control an engine in an altitude test cell. The details of the design procedure, linear model analysis and a summary of digital and hybrid simulation tests results are presented in this report.
