Control Systems is an important subject of Electronics and communications engineering. It normally comes in the 5th semester of the engineering. Control systems subject is of normally 4 credits across many colleges. Hence you need to score very good marks if you want good SGPA in particular semester. It will also boost your overall CGPA. However if you are planning to get into IT sector then it’s of no use. Simply pass the exam and concentrate on other subjects.
In Interviews also, there is barely any questions asked from control systems. Everybody asks from analog electronics and microprocessors. There are many good books available and highly recommended by professors for Control Systems.

Modern Control Engineering by Ogata and Kuo is quite more famous among students as a reference book. However you can take any one of these books and they will cover the whole syllabus for sure. We will be providing PDF study material for download in future. Till then you need to study from these books. Also try to solve previous year questions papers to know about the type of questions asked int he semester examination.
