Review on the control of hypersonic flight vehicles

The study on thecontrol of hypersonic flight vehicles (HFV) includes mainly theproblems of the cruising control of the air-breathing HFV and thereentry control of the non-power HFV. The studies on air-breathingHFV are mainly focused on two configurations: the winged-coneaccelerator configuration and the X-30 one; while the studies onnon-power HFV are concentrated on the X-33 and the X-38configurations. The dynamics and the control of the winged-coneaccelerator configuration, the X-30 configuration, and the reentrymode are respectively reviewed, and the hot issues in the researchon the control of HFV are highlighted.
