It is shown that, through Orthogonal Matching Pursuit, sparse higher-order functional series based ROMs can now be efficiently applied to complex 3D aeroelastic systems. Furthermore, an interpolation scheme for a nonlinear ROM library demonstrates excellent precision and robustness in modelling high amplitude limit cycles for a stabilator with freeplay and transonic aerodynamic nonlinearity.
