摘要：AbstractDue 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.
