Wikipedia: Van der Pol oscillator
Balthasar van der Pol reported 1927 strange phenomena about oscillations in a series resonance circuit containing a vacuum electron triode. Due to the nonlinear characteristic of the triode the autonomous circuit is able to maintain periodic oscillations, and with harmonic excitation it is able to produce chaos.
Note: For A = 0 autonomous periodic solutions are obtained.
For A = 1.0 forced periodic solutions are obtained.
For A = 0.45 forced chaotic solutions are obtained.
