Tracking Control of Combined Power Aerospace Vehicle in Climbing Phase

The trajectory tracking control method of the climbing section of the combined powered aerospace vehicle is studied. Firstly, the configuration of the combined power aerospace vehicle is designed and some parameters are given with reference to the same type of aircraft at home and abroad. On this basis, the longitudinal motion model of the climbing section, the thrust model and aerodynamic model are established. Secondly, the particle swarm optimization algorithm (PSO) and the automatic disturbance rejection control method (ADRC) are combined to design the angle of attack tracking controller of the climbing section. The parameters of the automatic disturbance rejection controller are optimized by using the PSO algorithm. Finally, the simulation of the angle of attack rejection tracking controller is carried out. The simulation results show that the tracking speed of the designed controller is significantly improved, which can effectively reduce the disturbance. Moreover, the controller has a good tracking effect on the input angle of attack command when the aircraft actuator is limited.
