### Linear Control System (LAB) EE-321

Linear Control system subject is a core subject offered in the Electrical Engineering program. The lab is comprised of the following portions

• In the first portions of the lab students are introduced to the brief background of MATLAB commands, Analysis of the first order systems and mathematical modeling of the physical systems and analysis of their behavior using MATLAB/SIMULINK.
• In the second portion students are familiarized with the transfer function, reduction of the multiple subsystems into a single system, analysis of feed back on the system output and the analysis of the transient and steady state responses of the first and second order systems.
• In the third portion students are able to analyze the system stability, analysis of the system type and steady state errors according to the test inputs and analysis of the root locus for the different systems.
• In the last portion students are able to design the PD,PI,lead compensator, lag compensator and the PID controler, for the desired reponse, of the systems.
