I have two master degree in Control engineering, and right now I am pursuing my Ph.D.. I have almost 15 years of experience in the subject. I can teach you Control Systems in 1 or 2 1-hour sessions a day, for a week. I believe it will be enough to cover all the subject you need. The cost is going to be 20$ a session, which altogether will be at most 280$. Please consider my offer and let me know if it suits you.
