Executive Summary
The course provides students with analytical and practical skills required for the synthesis and computer simulation of the DC motor automatic speed control systems. The course is preparatory for study in the field of various electric drives control systems.
Course objectives
Course objectives – to build students’ theoretical and practical skills on definition of electric DC motors parameters, to study of speed regulation methods and principles of constructing of a system of automatic control systems, to obtain knowledge of synthesis methods of various speed regulators of DC motor control systems.
To acquire these knowledge and skills students should know the structure and operation concept of electric DC motors with independent excitation. Moreover, they should be able to apply knowledge of the theory of automatic control for solving of regulators synthesis problems of speed stabilization systems.
The total scope of the course for postgraduate engineering education constitutes 20 hours: lectures – 10 hours, lab works – 5 hours, individual tasks – 5 hours. The course consists of 5 lectures, 2 laboratory works using the National Instrument educational platform with the DC Motor Control Trainer (DCMCT) board and individual tasks.
