Finite-time stabilization control for the flight mode transition of tiltrotors based on switching method

This paper studies the control problem of tiltrotor transition mode, which requires the regulation of nacelle inclination from 0 to 90 degree based on a finite-time switching control technique. Because of the dynamic characteristic of tiltrotor conversion, a single system model can not meet the requirements for control precision. A switched system is used to characterize the multitudes of the system. Then, based on the average dwell time method, the sufficient condition for finite-time stabilization of the longitudinal motion flight control system is developed. Finally, Simulation studies are used to demonstrate that a smooth transition of tiltrotor transition modes can be implemented effectively by the proposed switching control strategy.
