Active Aeroelastic Control using Multiple Control Surfaces Based on a High-Fidelity Reduced Order Model

Abstract

Using multiple control surfaces to actively suppress nonlinear transonic aeroelastic responses is a promising technology. A general method for designing a multiple-input multiple-output (MIMO) active aeroelastic control law is proposed. The Volterra series is applied to construct a high-fidelity reduced-order aeroservoelastic plant model suitable for transonic flow. The static output feedback method is also used to design a MIMO control law. The effectiveness of the proposed method to design the MIMO active aeroelastic control law is demonstrated by the Golandþ wing model with four control surfaces. The simulation results show that the MIMO active control law suppresses the transonic unstable aeroelastic responses of the Goland wing successfully with good control performance.
