The complex derivative Dα±jβ, with α, β ∈ R+ is a generalization of the concept of integer derivative, where α = 1, β = 0. We compute amplitude and period values of the periodic solutions of the complex order forced van der Pol oscillator, for variation of distinct parameters such as forcing frequency, forcing amplitude and parameters α and β. We find interesting quasi-periodic motion for certain values of the forcing frequency. This type of behaviour is seen in the continuous forced van der Pol oscillator.engForced van der Pol oscillatorComplex order derivativeDynamical behaviorconference object
