A second-order dynamic Terminal sliding mode control is proposed for near space vehicle which has characteristics such as large envelope,high speed,fast time-varying aerodynamic parameters,inevitable uncertainties,external disturbance and high control precision.

Principally based on the military background of persistent battlespace awareness,the current capabilities of C4ISR is introduced,and hence some problems related to the relative near space vehicles are brought forward and discussed,such as technical pushes,engineering designs,and conceptual applications.

The study can be a guidance for propwlsion system research other near space vehicles.

On this base,it is proposed that automatic collision avoidance(ACA) technique should be adopted for nearspace aerocrafts.

Application of near space vehicle in electronic reconnaissance

The paper introduces the concepts and characteristics of near space and near space vehicle,discusses the development status and trend of near space vehicle,analyzes application future of near space vehicle,and studies the relation between near space vehicle and air-and-space integration.

Since it is imported in Schriever-3 war game,the military application of near space vehicle has been a research hotspot.

A fault diagnosis and fault-tolerant control scheme using adaptive observer is generalized to near space hypersonic vehicle(NSHV) to deal with actuator fault.
