Abstract

Abstract The tilt-rotor aircraft has the advantages of high flexibility, low energy consumption and high speed, however, it faces the problems of complex operation and control difficulty. To solve the optimization problem of autonomous landing track of mobile platform, a Gauss pseudospectral method is used to design the landing trajectory of the tilt-rotor with optimal energy and time consumption. Firstly, an autonomous landing trajectory optimization problem model is developed for the tilt-rotor mobile platform. Then, the non-linear planning problem is solved, and finally, the optimal trajectory is put into the control program for control simulation. The simulation results show that the trajectory optimization based on Gauss pseudospectral method can meet the constraints well, which is in accordance with the time and energy consumption of the control program. Meanwhile, the control program simulation results can also keep up with the designed trajectory. It is proved that the Gauss pseudospectral method could design the autonomous landing trajectory with high accuracy and high performance.
