DOB Identification and Anti-Disturbance Control for Hypersonic Flight Vehicle Systems

In this paper, a novel DOB identification and control algorithm is developed for hypersonic flight vehicle. The DOBC technique is combined with the DNNs Models so as to identify attitude and velocity in the presence of disturbance. By using an adaptive method to adjust the weight matrices and compensate the unknown parameters, the control input is built with the Nussbaum gain matrix and feedback control gain. The stability proof is provided by using Lyapunov method. Finally, the simulation results shows DOBC technique is combined with DNNs models can obtained satisfactory dynamical identification and anti-disturbance performance.
