Control System Laboratory


Control Systems Lab focuses on technical implementation issues of classical control theory in the frequency domain and modern control theory in the state-space. This laboratory is having different setups for the study of various topics of control systems, like Control of Servomotors, synchros and PID controllers. In addition to conventional experiments students will use Matlab software. This lab is useful for the students for the design projects related to various controllers like P,PI and PID.
