An aero-engine U-control method based on LPV model

Abstract

Abstract Due to the harsh working environment and various constraints, the engine control unit (ECU) has very limited computational ability and few control methods can be applied to the real-word ECU maturely. Developing advanced control methods with good performance as well as low computational complexity is the research focus in the control area for the next generation aero-engines. The study reported in this paper combines the LPV model of aero-engine process with U-model control concept, which simplifies solving difficulty and avoids complexity of traditional LPV variable-gain controller. The results of Matlab-Simulink simulations demonstrate clearly this U-control method based on LPV model can be successfully used for designing quality aero-engine speed control system. It ensures a good control performance while guaranteeing stable operation in the proximity of chosen equilibrium steady-state thus demonstrating a considerable application potential.
