Intelligent Conversion and Reconfiguration of Tiltrotor Aircraft

Abstract

Tiltrotor aircraft has a great development prospect in civil aviation or military field due to the features of vertical lift capability hovering capability and high cruise speed To develop an integral control system of tiltrotor the contents of this paper was mainly divided into two parts flying control system design of tiltrotor’s flying mode conversion and reconfiguration control system design Firstly the dynamics model of the tiltrotor aircraft was built Refer to the V-22 this paper constructed a complete mathematical model to prove the control system’s performance Secondly the incremental nonlinear dynamic inversion (INDI) control architecture was proposed Helicopter mode controller and fixed-wing aircraft mode controller were respectively designed to make the tiltrotor accomplish flying missions After that the reinforcement learning with deep deterministic policy gradient algorithm was imported to complete the conversion of tiltrotor’s flying mode Finally the reconfiguration control system based on the INDI architecture was established With the multiple control surfaces this paper enabled the idle control paddle to offset the malfunctional control paddle In each part of control systems designed below this paper planed several scenario simulations to present the performance The result indicated that the flying control system design of tiltrotor’s flying mode conversion and reconfiguration control system design were feasible
