摘要：
Mass-actuated UAVs have the advantages of higher aerodynamic efficiency, better stealth performance and simpler wing structure. This paper proposes a single-slider mass-actuated UAV layout scheme with smaller time delay and simpler structure, and analyzes the influence of the slider parameters on the dynamical characteristics of the UAV. On this basis, the ideal installation position of the slider is given, and the change of the control efficiency of the mass-actuated scheme with the speed is studied. Aimed at the characteristics of strong coupling and nonlinearity of the mass-actuated UAV, an active disturbance rejection controller (ADRC) is designed based on the particle swarm optimization algorithm (PSO). The expanded state observer estimates the total disturbance term including coupling and parameter perturbation, and performs dynamical compensation at the same time. The simulation results confirm that the designed controller has good robustness and effectiveness. © 2022, Editorial Board of JBUAA. All right reserved.
