Tiltrotor aircraft possesses redundant actuators in take-off phase and its flight control is more complicated than ordinary aircraft because the structural and dynamic characteristics keep changing due to tilting rotors.
One of the fundamental bases for flight control is trim, which provides steady flight states under various conditions and then constructs the reference trajectory.
Tiltrotor aircraft trim models are described by multivariate nonlinear equations whose initial values are difficult to determine and bad initials could lead to incorrect solution for flight control.
Therefore, an innovative trim method is proposed to solve this issue.
Firstly, genetic algorithm (GA), which possesses strong capability in searching global optimum, is adopted to identify a coarse solution.
Secondly, the coarse solution is further refined by the Levenberg-Marquardt (LM) method for precise local optimum.
The innovative trim method combines the advantages of these two algorithms and is applied to a tiltrotor aircraft’s flight control in the transition process of incline take-off.
The limitation of trajectory is discussed, and tilt corridor is constructed.
Finally, the incline take-off simulations are conducted and the effectiveness of the proposed trim method is verified through good match with the designed reference trajectory.
