can try, basically a motor-sensor loop can "hold position" by noticing when it has gone past some threshold then corrects in the opposite direction ... rinse and repeat. Some systems may have thresholds that cause the rudder to "quiver" while staying on course, To an intelligent creature exquisitely sensitive to things quivering in the water this could be a major annoyance. the main types of motors likely used in this application are Servos and Steppers https://en.wikipedia.org/wiki/Servomotor https://en.wikipedia.org/wiki/Servomotor https://en.wikipedia.org/wiki/Stepper_motor https://en.wikipedia.org/wiki/Stepper_motor Here is a page that describes the behavior and calls it "hunting" https://www.motioncontroltips.com/what-is-hunting-in-the-context-of-motion-control-and-how-is-it-addressed/ https://www.motioncontroltips.com/what-is-hunting-in-the-con...
