Abstract :
We use retrospective cost adaptive control (RCAC) to control the thrust generated by a scramjet. A quasi-one-dimensional version of the mass, momentum, and energy conservation equations of compressible fluid flow with heat release is used to model the physics of the scramjet. First, we study the dynamic behavior of the scramjet model. Then, we apply system identification techniques to fit a linear model to the data generated by the scramjet model to investigate the dependence of scramjet dynamics on the Mach number. Finally, we use RCAC to maintain the commanded thrust in the presence of a disturbance in the Mach number.
