There seems to be a small error(?) in the calculation of the voltage for xdot: When the phase portrait goes through a maximum (see below), the “vertical” part should be right at xdot=0. Instead, it’s at about 0.1 V. This could be due to tolerances in components…?
This could be a hardware problem, but my guess is that it is a rounding problem in the draw axis functions.
