I have no idea if this poses some safety risks, but it worked when I was a student with a cheap induction stove. You can simply put a pair of kitchen clots under your pan to "dampen" the induction and use higher levels that do not cycle between on and off.
Again, I don't know the safety characteristics of induction so maybe I did something really stupid...
Mine pulses for the lower settings but has continuous control for the higher settings.
I believe higher-end stoves will either not pulse or pulse fast enough to effectively be continuous when you factor in the thermal inertia of the pot.
(It's possible I've only ever encountered crappy induction cooktops...)
