Abstract:

The purpose of this work was the investigation of aircraft control requirements for high speed, low altitude penetration. The control techniques used were, in all cases, based upon optimal control theory. The principal means of investigation was real time simulation of pertinent physical dynamics and breadboard mechanization of the control computation. Investigation was conducted with two systems identified as the linear and nonlinear system. In the linear case, further details potentially detrimental to the performance of the system previously studied were scrutinized. The nonlinear system effort was concentrated upon the synthesis of a system based upon an extension of the optimization theory previously used. The results further support the feasibility of an operational linear system. The results with regard to the nonlinear system are significant and also show the feasibility of synthesizing such a system. Good performance, which exhibits a substantial advance toward an ultimate ideal, was obtained over one terrain sample. More investigation of the nonlinear system is required to obtain comprehensive results.
