Output (\({\tilde {\kappa }_2}\)) of the FLIS of the proposed method. (a) different stiffness uncertainties and sinusoidal gust\({w_0}=0.07\); (b) different stiffness uncertainties and graded gust\({w_0}=0.07\); (c) different stiffness uncertainties and triangular gust\({w_0}=0.7\); (d) different stiffness uncertainties and triangular gust\({w_0}=2\).
