Adaptive Active Disturbance Rejection Control for Multiple Hypersonic Vehicles Under Complex Environments

Abstract

For the fact that the hyper-vehicle is susceptible to external disturbances in the active segment, causing it to deviate from the preset trajectory and affect the control accuracy, an adaptive active disturbance rejection controller (ADRC) is designed based on the backstepping technology, so that the multiple hypersonic vehicles can still maintain a stable attitude flight under disturbance situations, and maintain a good tracking effect to satisfy the system performance requirements. First, establish a mathematical model of the hypersonic vehicle containing the perturbed signal. Second, based on the backstepping technology, the controller is designed under the anti-disturbance conditions of the vehicle, and the deviation correction control is carried out. Then, the stability of the designed controller is proved by Lyapunov stability theory, so that it can meet the requirements of track control and achieve precise control. Finally, the rationality of the designed controller is verified by simulation experiment.
