MULTIBuckle Strange Attractors in a PWL VanDerPol type system

See my paper :
Ref ,

in the
Int. Journ. of Bifurcation and Chaos **9**(6), 1009-1039, (1999),
(IJBC).

The nonautonomous VanDerPol system is

dx/dt = y-f(x),
dy/dt = -alpha.x + b.cos(t) ,

f(x)= x^3/3 - x, (alpha and b parameters).
In the ref. given above, I modified f to get
some new strange attractors showing `multibuckles' solutions:
