Ok - a couple more dummy questions from the peanut gallery...

I can see why one would want to *precisely* tune the PI loop for a servo motor. I WANT MY ROBOT arm ***here*** yesterday!

Other things can have much more relaxed requirements. I'm setting up a VFD for an industrial ag pump. In this case it's actually better to slowly increase speed.

It seems to me there's lots of room for a more relaxed set of requirements in a car. For example, there's all the slop (gear mesh, etc) and inertia of the drivetrain. Then there's the mass of the car. It seems that even with a perfectly tuned servo-motor type control, you'll still be limited by physics for the car.

Could the auto(mobile) tune make use of this?

Also, I'm looking for some good information about spec'ing the bus capacitor. I'll be using the SBE film capacitors. However, I haven't been able to find good info about capacitor size - just a lot of hand waving and some questionably wrong papers.
