I have been working on this cruise control for quite some time and now that it seems to be working, I would like to add integral and derivative control to it. I purchased an AUDIOVOX CRUISE CONTROL CCS-100, but it just would not stay active, so I used some of it's parts and designed my own, but it over and under shoots a lot if the engine isn't pulling a fair amount of load. This is the same circuit as in time step error, but with the lt1001 op amp instead of a lm3324 so it simulates. Hope this isn't double posting.
It is a vacuum activated system and R2, R1, and R7, are the valves that let air in and out of the vacuum chamber that operates the throttle. R2 VAC lets the vacuum in, and R1 VENT and R7 DUMP let air in.
I will be trying to figure this out as I go, but would appreciate some help and advice.
Thank You,
