Professor in charge: Dr. Mehmet Dal
To reinforce the theoretical knowledge given in the course, students must submit 4 Lab reports regarding DC/ACmachine dynamic modeling, analysis, and simulation; as well as 2 project reports regarding AC machine control design and implementation. The students deliver reports answering specific questions regarding the design of closed loop control of AC machine drive systems and its dynamic and steady-state performance. In the written examination students answer questionsunder time pressure and without helping material to demonstrate theoretical knowledge of control system designmethods as well as of the design tools and parameters. Homework contains both written and/or computer simulationsusing MATLAB/Simulink. Lab sessions scheduled in advance are carried outpartially in the classroom. But ACmachine drive control should be performed in Lab. While the lab session is carried out in a group, the lab reports areindividual assignment.
Grading: Theory 40% ( Mid-term Exam 15% Final Exam 25%), Laboratory 60% ( 4 Lab with post-lab report: 30%, 2 Projects with formal report: 30%)

After successfully completing the course, students are able to grasp the basic background on Linear FeedbackControl Systems of DC/AC machine drives, apply analytic and computer based feedback control design methodssuch as Root Locus, Frequency response, as well as state variable systems and digital design for DC/AC motor,understand basic analysis and design of casade-loop feedback control systems, become familiar with the use ofMATLAB/Simulink for design and simulation. In the lab sessions, students are able to gain good practical experiencesin implementing well-known design methods with the use of a small real physical industrial plant (which is a DSPbased PMDC motor drive system, equipped with RCP tools which allow to be programmed with Simulink). Moreover,students become familiar with experimental implementation of motor drive control system integrated with RapidControl Prototyping (RCP) tools.
An innovative method based on creative classroom, following applied theory and student-centered learningapproaches is applied. An intuitive way will be used to simplify the conceptual understanding of control subject bygradually building the required knowledge on real life examples that students are familiar with. A flexible DC motordrive system, which is combined with digital controller and Rapid Control Prototyping (RCP) tools, will be used todemonstrate implementation of designed control systems in classroom. Therefore, with the use of the experimentalsystem, simulation and real-implementations can be conducted in parallel. This opportunity facilitates quick learningand more practical understanding of the most common control methodologies to reflect about the problems.
