Active aeroelastic wing design for gust load alleviation and flutter suppression

摘要

The purpose of this study is to use piezoelectric actuators and normal ailerons in suppressing flutter and reducing the gust response of a wing. ^LQR with output feedback is used in the control system design. ^For the aeroelastic control system design, two different configurations are considered: elastic modes for the feedback and self-sensing actuators. ^The rms value of the gust response for the flexible modes and the control performance index are used as a metric to compare the control performance for gust load alleviation. ^Using the initial and optimized wing configurations, a GLA system is designed. ^The control performance index and the gust response rms are compared. ^(Author)
