Research on Manipulation Strategy and Flight Test of the Quad Tilt Rotor in Conversion Process

The quad tilt rotor (QTR) has the problem of manipulation redundancy due to helicopter and fixed-wing mechanisms. Solving develop an effective strategy is critical for QTR during conversion flight. A novel based on states proposed in this paper solve mode. longitude controlled by angle nacelle mode course speed error propellers Active Disturbance Rejection Control (ADRC) adopt into flight control law, which can observe compensate internal external disturbance. simulation test are carried out verify results show that reasonable.
