“…Many fundamental nonlinear oscillation models, such as Duffing, Van der Pol, Rayleigh, Liénard, and Mathieu, have been extensively studied to describe nonlinear phenomena, such as nonlinear resonance, chaos, bifurcation, limit cycle, hysteresis and jump, analytic solutions, plasma oscillations, and noise effects [2]. Other than the studies on fundamental oscillation models mentioned above, many composition forms of fundamental oscillators also attract the attention of researchers, such as Duffing-Van der Pol oscillator [3], Mathieu-Duffing oscillator [4], Rayleigh-Duffing oscillator [5], Rayleigh-van der Pol-Duffing oscillator [6], and Mathieu-van der Pol-Duffing oscillator [7]. Among the composition forms of oscillators, we, in this paper, focus on generalized mixed RayleighLiénard oscillator as follows [8]:…”
