Slow loop timing could easily cause both overshoots and undershoots.

Additionally, one of our local teams used a slightly modified Bang-Bang to resolve the "The bang-bang sounded horrible" issue. What they did was increase the "off" state drive from "0" to 30% power.

They also added a second case to completely stop the motor when not needed.
