This is the second part of how to sketch a root locus by hand. However instead of following the normal rules for sketching a locus that you'd see in a book, I decided to explain the rules how I use them, and how knowledge of the shape of a root locus can help you design a compensator.

If you have annotations turned off you might miss the link to the Matlab video, you can find it here though:    • Gain a better understanding of Root Locus ...  

You can check out the math behind these rules from this online book. If you Google for it you can read the book for free through Google Books. Control System Principles and Design by Ernest O. Doebelin -- Starting at Page 305

Of course if you're looking for more of a classroom style lecture than you really can't go wrong with Prof. Madan Gopal at nptelhrd.    • Lec-30 Compensator Design Using Root Locus...  

Also, Ewald Erasmus made a great video on finding the gain k from a point on the root locus:    • Control Systems (EBB 320): Solving for an ...
