The board link is the website link, sorry for confusing you :)

Ah, I see.
The DE2-70 has plenty of logic for a PID controller. The lower-cost DE0-nano, BeMicro, and BeMicro-SDK boards would also have enough logic.
What is just as important, is what are your I/O requirements? Does your PID controller need an ADC or a DAC? How are you going to interface to the real-world?
You need to look at both the FPGA board and the interface boards, and make sure you can connect them together without too much work.
The DE2-70 and DE0-nano interface to boards via their GPIO headers. Terasic have some ADC/DAC boards.
The BeMicro and BeMicro-SDK boards have an 80-pin edge connector. You can connect a PROTO board to that header for interfacing to custom logic.
