Airbrake for a Supercar! - actuator controller??

[WagEng]

Hi,

I'm working on engineering an airbrake for a vehicle similar to what is on the new McLauren. I want a simple, lightweight controller for two 12v actuators. The controller will move both actuators [in lock-step with each other] over 100mm once a pressure sensor reads x psi. Once that sensor signal drops below x psi, the actuators will return to zero regardless of where they are. In other words, they don't have to complete their stroke.

I've found some decent actuators (although suggestions are wanted). I desperately need a simple, lightweight controller. I'm a mechanical engineer with some controls experience (PLCs etc).

Thanks!
Todd
