I'd be inclined to go digital - PWM with a $2 Arduino is pretty easy and
you have analog inputs available for feedback.

I use these to control 24v 250w wheelchair motors I use on my walnut
washing machine:
and an Arduino Nano clone is also pretty cheap:

I have spares of both if you want to try them - I'll not need replacements
until the next walnut harvest season (assuming anything goes wrong with
what I have!). I can bring them to the next meeting ;)
