Adaptive decoupled fuzzy sliding-mode control of a nonlinear aeroelastic system

A model of an adaptive decoupled fuzzy sliding-mode control (ADFSMC) for a nonlinear aeroelastic system, is presented. This model describes the nonlinear plunge and pitch motions of wing section, using a single trailing-edge flap as the control input. The approach involves dividing the aeroelastic system in to two subsystems, and the constructing two sliding surfaces using the state variables of the decoupled systems. The simulation results show that the proposed ADFSCM can achieve better transient performance the HGSCM at the price of larger control effort.
