The tilt rotor aircraft is capable of both low-speed hovering and high-speed flight, which has a larger flight envelope. However, during its transition phase, due to the change of the mechanical structure, the dynamic characteristics of the rotor and the aerodynamic characteristics of the fixed wing have intercoupling, which present strong nonlinear characteristics and weak anti-disturbance ability. To address this problem, this paper proposes an anti-wind disturbance decoupling control algorithm based on the improved active disturbance rejection control (ADRC) for the transition phase of the tilt rotor aircraft, and presents an improved particle swarm optimization (PSO) algorithm to optimize the parameters of the control system in the transition phase. According to the simulation results, our algorithm can provide better anti-disturbance ability than the traditional algorithm, realize decoupling control between different states, and effectively improve the flight safety in the transition phase.
