Abstract: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.
