Adaptive Control of a Generic Hypersonic Vehicle
This paper presents an adaptive augmented, gain-scheduled baseline LQR-PI controller applied to the Road Runner six-degree-of-freedom generic hypersonic vehicle model. Uncertainty in control effectiveness, longitudinal center of gravity location, and aerodynamic coefficients are introduced in the model, as well as sensor bias and noise, and input time delays. The performance of the baseline con...
متن کاملHypersonic Vehicle Tracking based on Improved Current Statistical Model
A new method of tracking the near space hypersonic vehicle is put forward. According to hypersonic vehicles’ characteristics, we improved current statistical model through online identification of the maneuvering frequency. A Monte Carlo simulation is used to analyze the performance of the method. The results show that the improved method exhibits very good tracking performance in comparison wi...

متن کاملNumerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
متن کاملNonlinear Adaptive Dynamic Inversion Applied to a Generic Hypersonic Vehicle
Flight control of hypersonic vehicles is challenging because of the wide range of operating conditions encountered and certain aspects unique to high speed flight. A particular safety concern in hypersonic flight is the risk of an inlet unstart, which not only produces a significant decrease in thrust but also results in a change to the aerodynamics and thus can lead to the loss of the vehicle....
