Abstract

Abstract:

Based on Takagi Sugeno model of fuzzy system, a fuzzy model is established of flight control systems. Global asymptotic stability for this kind of fuzzy system is discussed. It gives a sufficient condition for fuzzy systems with global asymptotic stability and a method to design fuzzy controllers satisfying certain conditions. The obtained results are employed to analyze longitudinal motion of an aircraft made in China. The analysis shows that this model is proper and the method is effective.

Key words: flight control system, fuzzy system, asymptotic stability, fuzzy controller
