Question: DEplot of elliptic nonlinear oscillator

Hello,

I would like to plot an non linear oscillator.

The equations are the following:

r:=sqrt((x(t)/a)^2+(z(t)/b)^2);
eqx:=diff(x(t),t)=alpha*(1-r^2)*x+wa/b*z(t);
eqz:=diff(z(t),t)=beta*(1-r^2)*y+wb/a*x(t);
EqSys:=[eqx,eqz];

The constants are the following :

alpha:=1:
beta:=1:
a=0.4:
b=0.2:
w=1:

I didn't manage with Deplots. May you help me to plot this oscillator?

Thank a lot for your help and ideas
