ロバスト制御におけるアクティブラーニングを目的とした遠隔実験環境の効果

This paper deals with the effectiveness of the remote experimental system for active learning in robust control. It is usually difficult to understand control theory so as to design and implement control systems only by following general theoretical development without practical system examples; however, it is difficult to introduce practical systems in lectures. In order to solve the problem, we have developed a remote experimental system which can be used over the Internet providing an active learning environment for students who learn robust control theory even outside lecture hours. The developed remote experimental system automatically carries out the experiment when parameter files of designed controllers are uploaded via the Web page, then the control experimental results are posted on the same Web page in about one minute. The developed system was introduced in a lecture, ‘Advanced Automation’, in 2015 and 2016, and used for the control experiment of robust active noise control of duct. By analyzing the usage of the remote experimental system such as the number of designed controllers and the frequency of executions, and comparing the results with the final reports submitted by students, we confirmed that the number of active students who work well with the design problem was increased by introducing the remote experimental system compared with the previous situation before the introduction of the system. Similar results were obtained from the questionnaire results.
