Switching performance optimal controller design for hypersonic vehicle model

This paper addresses the problem of switching performance optimal control for the longitudinal model of the generic hypersonic air-breathing flight vehicle. For the widening flight envelope of hypersonic vehicle, the multiple-mode switching control is an issue that have to be considered. The approach presented makes use of the bumpless transfer technique and gives a switching performance optimal controller design method for coping with bumps and undesirable transients in multiplemode switching systems. Simulation results for the generic hypersonic vehicle model show the effectiveness of the proposed design method.
