Public award description
IGF::OT::IGF CONTROL OF EXTREMELY LIGHTWEIGHT, LONG ENDURANCE AIRCRAFT POSES A CHALLENGING AEROSERVOELASTIC (ASE) PROBLEM DUE TO SIGNIFICANTLY INCREASED FLEXIBILITY, AND AERODYNAMIC, STRUCTURAL, AND ACTUATOR NONLINEARITIES. TO OBTAIN THE BENEFITS OF INCREASED AEROSTRUCTURAL EFFICIENCY, THE CONTROLLER NEEDS TO TRIM AT A SPECIFIED OPTIMAL SHAPE WHILE MINIMIZING STRUCTURAL FATIGUE FROM GUST DISTURBANCES. TAO SYSTEMS, TEXAS A&M UNIVERSITY AND UNIVERSITY OF MINNESOTA PROPOSE TO DEVELOP A DISTRIBUTED, PASSIVITY-BASED, ASE CONTROLLER (DPASC) USING SECTIONAL AERODYNAMIC AND STRUCTURAL OUTPUT-ONLY FEEDBACK. THIS SCALABLE APPROACH HAS THE POTENTIAL TO MINIMIZE THE IMPACT OF AERODYNAMIC / STRUCTURAL UNCERTAINTIES AND CONTROL SURFACE FREE-PLAY / SATURATION, WHILE GUARANTEEING GLOBAL ASYMPTOTIC STABILITY.
