Experimental Teaching Design and Implementation of Double Closed-loop DC Speed Control System

In order to deepen students’ understanding of the theoretical knowledge of electric drive control technology and double closed-loop DC speed control system, train the students’ ability to solve complex engineering problems and sense of cooperation and responsibility, according to the concept of “outcomes-based education”, combined with “course education”, a double closed loop DC speed control system of experimental platform has been designed, we set teaching goals, optimizing the teaching content, and the main experimental process and results are analyzed. The experiment shows that the double closed-loop DC speed control system with proportional integral regulator improves the static and dynamic performance of the system, and obtains good experimental teaching effect after years of teaching practice.
