No one can teach you control system basics on a forum, read Feedback Control Systems (5th Edition) by Charles L Phillips. You can get a digital version on CourseSmart rather cheap.

Perhaps you should start by answering Studiots question and reading the indicated texts.

Posting the additional PDF doesn't change the initial responses.
