英文摘要: In order to improve the helicopter responsive ability during autorotation power recovery maneuvers, a new turbo-shaft engine control scheme is proposed in this paper. Using rotor flapping/lagging dynamics and an induced velocity model which is capable of capturing vortex ring characteristics, an integrated helicopter and engine model was developed to simulate autorotation process. By introducing a closed-loop with compressor guided vanes, a novel two-variable engine control law is devised using Linear Matrix Inequality Pole Placement method. This allows for a rapid adaptation of the helicopter to a large and fast needed torque variation required in autorotation power recovery. The transient performances and the robustness for the closed-loop helicopter-pilot system are validated for some...
