So what have you tried so far and where are you stuck?

Why do you come here in the last week of your 4 (or 5) week project?

Mind to attach your VI so we can tell you what you need to improve?

Did you take the LabVIEW training resources in the last 4 weeks?

(You know we will not do your homework for you, especially when you earn points/grades/whatever…)

Wikipedia has a nice description of PID control algorithms: did you implement the simple parallel form?
