Boundary Control of a Nonhomogeneous Flexible Wing with Bounded Input Disturbances
For researchers in aerospace control, this work provides a theoretical framework for boundary control of flexible wings, but it is incremental as it extends existing methods to a nonhomogeneous model.
This paper addresses boundary control of a nonhomogeneous flexible wing under unsteady aerodynamic loads, proposing a control law and proving well-posedness and stability in the presence of bounded input disturbances using semigroup theory and Lyapunov methods.
This note deals with the boundary control problem of a nonhomogeneous flexible wing evolving under unsteady aerodynamic loads. The wing is actuated at its tip by flaps and is modeled by a distributed parameter system consisting of two coupled partial differential equations. Based on the proposed boundary control law, the well-posedness of the underlying Cauchy problem is first investigated by resorting to the semigroup theory. Then, a Lyapunov-based approach is employed to assess the stability of the closed-loop system in the presence of bounded input disturbances.
