Abstract:

A critical assessment is made of the need for adaptive flight control systems and their associated complexities compared to non-adaptive systems for lifting entry vehicles, both manned and unmanned. The intent of the paper is to stimulate a little more careful thought as to whether an adaptive system is really essential in a given application. One might expect that the need for adaptive control would be somewhat different for manned than for unmanned vehicles performing similar missions. However, little attention has been given to these differences by proponents of various adaptive schemes. In any given application, the basic question which should be answered before committing oneself to an adaptive system is Given bounds on plant parameter variations or uncertainties and on disturbance inputs, and given acceptable tolerances on system response, what is the optimum, linear, fixed compensation control system non-adaptive.
