Any one familiar with my posts knows I've been playing with this power steering unit for quite while, I'm still trying to smooth off all the rough edges.

2014-12-25 POWER STEERING - Hysteresis.asc is the whole schematic with Hysteresis which will not sim.
2014-12-25 POWER STEERING - Hysteresisplay1.asc is a stripped down schematic with Hysteresis that will sim.
2014-12-25 POWER STEERING - Hysteresisplay2.asc is the same stripped down schematic with out Hysteresis the will sim.
The actual unit has a problem with one of the Gate feeds to the Coil driving FETs (Now changed to transistors), the feed on one side does not switch cleanly from on to off or off to on but hangs in the middle and oscillates, it did the before I added the Hysteresis also, but also had lots of spikes from the PWM. I also noticed that the hysteresis shifts the center of things to a higher voltage, as shown inb the .png attachment.
Does any one have any suggestions on how to make the Gate drivers switch cleanly?
