Robust Integral Sliding-Mode Control of An Aerospace Launch Vehicle

An analysis of on-line tiuionomotcs robust tracking controller based on variablestructure control is presented for an aerospace iaunch. vehicle, decentralizedsliding-mode controller is designed to achieve the decoupled asymptotic trackingof guidance commands upon. plant unccrtainiics and external disturbances.development and application of the controller fot un aerospace launch oehicledtlring atmospheric flighl in an erpcrimenicl setting is presented to illustrate theperjorttuuice of the control olqoriilin, against uniid qust. and internal dynam:icsuariaiions. the proposed sliding mode control is compared to non-linear andtime-varying gain sclieilulcd aiitopiiot arul its superior perjormomce is illustratedby simuloiion results. furthermore. the proposed sliding-mode controller isconvenient for irnplcm,cnt(!tion.
