This paper is a review of aeronautic and astronautic automatic control. After lecalling the three periods of the development of control theory(the period of classical control theory, the period of modern control theory and the period of large scale System theory) , the arti-rfical intelligence and expert system are briefly introduced , pointing out the trend of the further development of control theory. Then the aircraft; the spacecraft and the space shuttle automatic control are described.It is observed that the development of the automatic control techniques of these flight vehicles has a direct bearing on the development of automatic control theory.The more advanced of the theory, the greater improvement of the control sys-tem is. Finally it is concluded that the techniques of aeronautic and astronautic automatic control would be developed towards goal of digitalization , integralization and even intelle-dualizat ion .

本文是航空与航天自动控制的综述。首先回顾自动控制理论发展的三个时期:经典控制理论,现代控制理论和大系统理论时期;简要介绍人工智能与专家系统;并指出自动控制理论发展的动向。此后介绍航空器自动控制,航天器自动控制以及航天飞机的自动控制。通过分析看出,这些飞行器自动控制技术的发展与自动控制理论的发展密切相关。理论前进一步,控制系统也就提高一步。另一方面对自动控制系统日益增长的高要求又推动着自动控制理论的发展。最后得出,航空与航天启动控制将朝着数字化、综合化以至到下一世纪的智能化的方向发展。

Theoretical and experimental investigations of pneumatic lag characteristics in vehicle's pressure sensing devices is presented. An useful formula which can be accurately used to predict the lag charactevistics of pneumatic sensing system subjecting to pressure input with constant rate is given. The procedures used to experimental measurement of pressure lag are described. Comparisons of theoretical Calculations and experimental results are given and show they are in good agreement.
