To improve students' interest in learning, this paper proposes a Virtual Learning Environment (VLE) for the inverted pendulum control experiments in automatic control principle. The proposed VLE framework includes five levels: user interface, applications layer, models layer, platforms layer, and data layer, which facilitate the design, development, and implementation of the VLE system. And then, this paper constructs an intelligent Question-Answering (QA) model based on BERT, which can help the virtual tutor answer students' questions about the inverted pendulum control input by text or voice. Moreover, in order to improve the interaction and intelligence of the virtual environment, this paper builds a virtual agent model to simulate human behavior. Finally, the VLE system is designed and implemented. Students can learn automatic control principle through the inverted pendulum experiments in the VLE system. By setting the parameters of the typical control algorithm simulated by MATLAB and observing the control result in the virtual reality environment, students can understand the control principle more effectively. According to the primary evaluation experiments, the immersive virtual learning environment can help students enhance their learning enthusiasm. [ABSTRACT FROM AUTHOR] |
