Abstract
In order to help students understand the basic control theory, the authors have proposed a motivational lecture, where students get personal experience in advance of theoretical lectures. To realize the motivational lecture, the authors have designed a portable and inexpensive control experimental system. However, the system has some points to be improved in terms of costs, size and functions. Hence, the authors revise the experimental system to be more portable and less expensive. Moreover, the system is expanded so that education of other fundamental concepts is possible. This paper shows the design details of the experimental system.
