Description

technical field [0001] The invention proposes a control law design and verification method of an aeroengine distributed control system considering time delay, and belongs to the field of aeroengine control algorithm design. Background technique [0002] The background of the present invention is the design and verification of the control law for time delay of a certain type of turbofan engine distributed control system. [0003] The aircraft engine is the heart of the aircraft, and its performance is directly related to the flight safety of the aircraft. With the improvement of people's requirements for aero-engine control, the complexity of its control system design is also increasing, and the traditional centralized control architecture has been difficult to meet the complex control requirements. In order to further improve engine performance, reduce total engine weight, increase system versatility, and reduce system development and maintenance costs, the current aero-eng...
