Improved trajectory optimization for variable-span aircraft based on pseudo-spectrum method

Based on the improved combined algorithm, the trajectory optimization design of variable-span aircraft is proposed. The paper first established the kinematic model of the variable-span aircraft and the model of the trajectory optimization problem. The Particle Swarm Optimization algorithm and pseudo-spectral method are combined to optimize the trajectory design, using the trajectory solution obtained from the Particle Swarm Optimization algorithm as the initial solution for the pseudo-spectral method. Simulations are designed and implemented for two scenarios and tasks. The results show that the variable-span aircraft shows superior performance, able to execute flight tasks more quickly and at higher speeds.
