Practice of CDIO in Course of DC Motor Drive and Control System

DC Motor Drive and Control System is a primary course for Electrical Engineering and Automation. This course is a quite comprehensive and practical engineering course to be feasible to introduce the CDIO teaching mode. Based on the detailed analysis and revision of teaching syllabus and content, a third-level project is presented according CDIO standards 5, 7, 8 and 11. The main circuit and DC motor are provided by teachers. Students are responsible for the design and implement of control circuit. The major knowledge of this course together with other learned courses is sufficient to complete the project. This plan will help students improve their hands-on skills, integrate their comprehensive professional knowledge, stimulate students’ motivations to use more professional and advanced design methods and apply them in the project. Students are divided into groups and teams to perform the tasks as followed. Firstly, the project application report includes research theories, content, research goals, key subject problems, research plan, feasible analysis, and so on. Secondly, research report need to be completed, which includes regulator design results, drawings of all the designs, system simulation and PPT for final answer. Finally, manufacturing and function test. This part includes schematic diagram and PCB design, welding of hardware circuit, and function test and competition. The score of each student is given by teachers according to the implementation level, research report and attendance. The attendance will be checked strictly during the course. Students should join the project research on time. Absence without reason and early quit are forbidden. Extra score will be given to the outstanding student. Students carry out the project design and experiment, and finally accomplish scheduled tasks by means of test and answer. Through this practice of CDIO, students obtain important experience on hands-on skills, global vision and team work spirit.
