The comparison between the analytical and numerical results of the first-order moment of system stationary state response \(\langle x(t)\rangle _\textrm{as}\) with different driving frequencies: (a) \(\Omega = 0.2\pi\), (b) \(\Omega = 0.4\pi\), (c) \(\Omega = 0.6\pi\). The other parameters are set as \(m = 1\), \(\alpha = 0.5\), \(\tau = 0.1\), \(\gamma = 1.5\), \(\omega = 2\), \(\varepsilon = 1\), \(\sigma = 0.3\), \(\lambda = 0.5\), \(A = 1\).
