I dont understand what U8/U9 is or how it works?
voltage controlled potentiometers, they simulate they simulate the Wheatstone arrangement of the 2 potentiomete sensor on my steering unit, it has 4 leads, red v+, green v-, black wiper, white wiper. On the right side the Quad comparator, the output from U8 and U9 are compared to sawtooth wave to give PWM
What is V1? voltage waveform for U8/U9
Why are the flat spots on V(whiteP-1) and V(blackP-2)? the flat spot the dead spots as you go from left turn to right turn with a pause at the crossing, not really needed, but it was intended to give me my needed pulse width at the crossover point, it doesn't.
Why do you have two comparitors? H-Bridge driver control
Why do you need to have the weird AND gate made out of two nFETs? this is what I need the pulse width for, when the outputs from the left side of the quad comparator are both high, at the crossing, both fets provide a path to ground to take another nfet's gate to ground and stop the current flow through an SCR and turn it off.
Why do you ever use "uic" as part of a simulation? because I'm impatient and I run the same sim several times with very minor changes, just to see what that change creates, for example, with a LM317 in the circuit, non uic sims can take a while and real often, the information I want shows up at the beginning of the plot.
This last project is 4 separate files added to a composite file, so if I'm trying to figure one thing out I don't add the parts not needed so sims are quicker.
Here is the complete file.
Thanks for asking questions, while trying to make sure you understand what I'm doing, I get a better understanding of what I'm doing and I think I found the solution, Hysteresis seems to do the trick, at least on paper, now to go try My new values.
Thanks,
Jeff
