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 contr...

Abstract Current research on quadrotor modeling mainly focuses theoretical analysis methods and experimental methods, which have problems such as weak adaptability to the environment, high test costs, long durations. Additionally, PID controller, is currently widely used in quadrotors, requires improvement anti-interference. Therefore, aforementioned has considerable practical significance for ...

This article proposes a computationally efficient adaptive robust control scheme for quad-rotor with cable-suspended payloads. Motion of payload introduces unknown disturbances that affect the performance controlled conventional schemes, thus novel controllers both integer- and fractional-order dynamics are proposed trajectory tracking payload. The acting on due to motion estimated by utilizing...
