Switching Frequencies for Industrial/Automotive Solid State Relays.

I have been working on a large outdoor robot driven by "Power Wheels" children's car motors for a while now (http://boomsandbots.blogspot.ca/search/label/Project%20Killzone is the section of my blog devoted to it) and I decided to build my own high power motor controller rather than buy one. As you can imagine, it has been a journey filled with smoking electronics, learning, and rebuilding. Anyway, I have relays set up to control the direction of the motors, and that part works quite well, but the problems I have had is with the speed control section.
