Characterization of Mathematical Modeling of Control at Undergraduate Level Using Unity Software

In order to help in the understanding of the analysis of the mathematical modeling of the control system (mechanical and electrical), this research describes how the Augmented Reality (AR) technique can play an important role in the user's interactivity with the problem. The idea of the project involves the creation of an Augmented Reality app designed in Unity software. Through an image scanned by a cell phone camera, it will project the free body diagram of the control system in 3 dimensions so that the user can have a general view of the problem to be treated, an explanation of mathematical modeling through a video, and a graph with unit scale input. The results of the research focused on the validity of our proposal and were evaluated by 28 students surveyed from the Mechanical and Electrical Engineering program whose analysis was carried out under the aspects, whose results were positive, whose Design aspect obtained 0.73, Pedagogical 0.78, Content 0.76, and Technical 0.75. In addition, a high value for the reliability level was obtained, with a Cronbach's alpha of 0.942. According to the research, it is concluded that the implementation of an app using the Augmented Reality technique using Unity software for the analysis of the mathematical modeling of the control system has a positive impact on the students due to the design of presenting the free body diagram and the interactivity, which have proven to be key elements for the understanding of learners.
