This course is a compulsory specialty basic and core course for electric engineering students. It helps the students to obtain the fundamentals and techniques of automatic control theory; to gain an understanding of system by control concepts; and to solve engineering problem by control system. The course involves modeling of control system, system analyses, system design. Simulation and experiments are also presented as supplementary. It presents modeling of control system by transfer function, system response analyses in time domain, root-locus method of analysis of control system, frequency-response method of analysis and design of control system.
