摘要：Now a days nonlinearities are considered as a rule not an exception. Backstepping is a Lyapunov basedrecursive control algorithm, which is a strong tool for a class of non-linear systems. But Backstepping procedurerequires exact plant model which is not the case with Adaptive Backstepping Controller design. In this paper, bothBackstepping and Adaptive Backstepping Control are analyzed in detail and are applied to the stabilization oflongitudinal dynamics of a reusable launch vehicle. For Backstepping controller design, typical values of theparameters are taken but for the Adaptive Backstepping Controller design, all the parameter values are treated asunknowns and by Certainty Equivalence principle, the estimated values replaces the unknowns. From the simulationresults, it is clear that Adaptive Backstepping Controller gives the best results compared to the Backstepping controller,particularly for parameter uncertainties.
