Abstract:

A study was made of the use of a terminal controller technique in the guidance of a capsuletype reentry vehicle to a desired landing point. Two-degree-of-freedom equations are used to describe the vehicle dynamics. The guidance system continuously predicts the final error in the range traveled. The predcted error is used to control the angle of attack in an on-off mnner. The result indicae control to wihin 1 degree in rnge over the total range capability of the vehile and a mnimum number of control corrections. uthorA-256 079N2ner.
