hi bros.
am freshe graduated control engineer , closed to process control and recently become a raspberry interested and i want to know the opportiunities to build process controller using Rasapberry pi and also threats ( scan time of reading analogs , reliability , number of i\o ..etc
all the best 
you can use the raspberry pi as a process controller for sure, but i would say use the Beaglebone Black instead because of its faster processing speed and easy to use GIOP ports, the raspberry pie was designed as a low cost easy to use Linus computer, whereas The BeagleBoard family was originally designed to provide a relatively low-cost development platform for hobbyists.. I am just saying that you have a better choice rest is up to you, good luck for your project..
