A New Approach to Aircraft Robust Performance Analysis

A recently developed algorithm for nonlinear system performance analysis has been applied to an F16 aircraft to begin evaluating the suitability of the method for aerospace problems. The algorithm has a potential to be much more efficient than the current methods in performance analysis for aircraft. This paper is the initial step in evaluating this potential. Keywords: aircraft performance, uncertain system, nonlinear performance. 1 Introduction Real world systems are necessarily nonlinear and the range in which these systems can operate safely and within specifications is of paramount interest to both system designers and their eventual users. Typically, controllers are designed and analyzed using linear methods at different operating conditions. In the final design stages, the nonlinear system is analyzed through repetitive simulation to determine its actual performance. The currently accepted practice in industry and elsewhere is to select a number of potential operating paramete..
