Abstract: | In this paper a complex-order van der Pol oscillator is considered. The complex derivative Da±jbD^{\alpha\pm\jmath\beta}, with α,β∈R
+ is a generalization of the concept of integer derivative, where α=1, β=0. By applying the concept of complex derivative, we obtain a high-dimensional parameter space. Amplitude and period values
of the periodic solutions of the two versions of the complex-order van der Pol oscillator are studied for variation of these
parameters. Fourier transforms of the periodic solutions of the two oscillators are also analyzed. |
