Analog Simulation and Analysis of a Non-Linear Self-Adaptive Flight Control System

Abstract

An analog simulation was conducted for the longitudinal axis of the General Electric Self-Adaptive Flight Control (GESAC) System, as proposed for use on the X-15 aerospace vehicle. The gain-changing dynamics of the non-linear loop are considered briefly and the effects of noise on system operation are observed. A method of optimizing the system simulation by first considering the non-linear loop independently is described. It is shown that this system is capable of maintaining aircraft stability throughout the X-15 re-entry flight profile and that noise introduced during system operation do s not seriously degrade system performance.
