Magnetic levitation system is one of the most familiar experimental system in the field of control engineering because it is easy to understand its phenomenon, its differential equation is so simple, it is an unstable system and so on. To synthesize a controller which makes it stable based on the modern control theory and simulate the controlled system, a personal computer has been in common use. In this paper, we propose a new aided system utilizing the graphing calculator Voyage200 instead of the personal computer. Voyage200 is of handheld size and has high portability. Furthermore, it has high performance such that it can do computer algebra and draw the results of simulation and/or experiment on the large display. Since the second semester in 2005, we have been adopting Voyage200 for our student experiment. In this paper, we introduce our experimental system and describe the educational effects of Voyage200 by means of answers of questionnaires to students after experiment.
