A practical design approach to automatic model construction and controller design for F16 aircraft

Abstract

This paper presents a practical design approach to automatic model construction and controller design for the F16 aircraft. The automatic model construction and controller design are realized using the framework of a Takagi-Sugeno (T-S) fuzzy modeling and control. Any trimmed equilibriums in addition to the complicated dynamics describing in an F16 aircraft simulator are considered and automatically converted to T-S fuzzy models around any trimmed equilibriums. A linear matrix inequality based design is carried out to automatically obtain stable nonlinear T-S fuzzy controllers according to the considered trimmed equilibriums. Control performance of the designed controllers are tested for the original dynamics (not T-S fuzzy models). The testing results demonstrate the utility of the practical design approach to automatic model construction and controller design.
