Abstract

Increasing requirements from flight control demand fast regulation of engine control systems. This has motivated research on advanced control of turbofan engines. One of the attempts is to employ nonlinear design techniques in consideration of the inherent nonlinearity of the engine dynamics. In this note, a finite-time based control approach is proposed for fast response control of turbofan engines. Results on control design are obtained that stabilizes the closed-loop system in a finite time. The proposed design is then validated though a numerical example. The study also shows that the proposed controller possesses good robustness to fuel flow pulsation and aero-dynamical coupling disturbances.
