Ah, the final year project on PLC.
So presumably this means you have already spent several other years studying PLC?
The one thing I would have expected you to learn during these other years studying PLC is that this is not the way to ask a question here if you really have any expectation of a sensible answer.
 
Simple answer is in your book.

output is Kp*deviation+Ki*deviation+Kd*deviation

there is some more to it. But if you search a book on PID control you will find it.
And Yes i will not give you a complete answer.
