The research on PDMC(performance deterioration mitigation control) of intelligent engine was performed.The PDMC consists of both loops

for example

the inner loop controls the rotor speed and the outer loop controls the thrust.As a result

it not only inherits the advantage of traditional control system

but also can realize the direct control of thrust as the direct thrust control.Meanwhile

it enhances the autonomous control of aero-engine.To verify the effectiveness of PDMC

simulations on a two-spool-mixed-flow-turbofan engine were performed.The simulation results show the efficacy and feasibility of PDMC technology.
