Control simply means to regulate, direct or command a system so that the desired objective is obtained as a result and System is an arrangement of physical component that are connected in such a manner so as to form an entire unit to obtain a certain object. On combining these two definitions, Control System forms an arrangement of different physical elements connected in such a manner so as to regulate , direct itself in order to obtain a certain objective. Control System is one of the most important topic in the B. Tech Syllabus of Electronics and Communication Engineering Students as it covers all the necessary facts and detailed mechanism that are used in our day to day life in terms of various machines. Thus in this post we have tried to made available Sample Paper for Control Systems Engineering to help students to secure good marks in this subject.
