摘要

This report deals with the automatic control of an aircraft in a terrain-following mode of operation. The primary concern of the report is the generation of an analytical control law which takes into account the main constraints of aircraft performance, those of maximum lift acceleration and a maximum climbdive angle capability. The approach taken is to solve the Euler-Poisson equation for a particular, but realistic, definition of an 'optimum' flight trajectory. The resulting solution of the Euler-Poisson equation contains a shaping parameter which allows a good bit of freedom in shaping the basic flight path trajectory to the characteristics of a particular aircraft. The control law is such that errors in prediction of present and future aircraft dynamic performance are manifested to a minimal extent, in the accuracy of present command to the aircraft. An application of the developed control law to the analog computer simulation of an aircraft formation flight subsystem is presented as an appendix. (Author)
