DC machines remote lab case study in Technical and Vocational University

Abstract

Practical study such as laboratory activity helps students to learn about engineering technical courses. New electronic technologies and the Internet of Things allow students and researchers to do experiments remotely. During quarantine due to pandemics such as Covid‐19 or when researchers and students are not present in the university, remote laboratories are used as a complementary teaching feature. In these conditions, the remote laboratories also allow the development of experimental‐based research. This paper presents the design and development of a remote interactive laboratory for the teaching and practical learning of DC machines at Technical and Vocational University. This laboratory is designed using the Arduino board to make a data acquisition card and actuator controller. Also, LabVIEW is used, which is remotely controlled based on the Internet and allows students to observe and perform experiments related to the DC machines course anywhere and anytime. In this laboratory, to better adapt to the Accreditation Board for Engineering and Technology criteria, the principle of teamwork to perform the experiments and achieve the final result has been considered. The case study results of a remote laboratory in Mohajer Faculty present the students' understanding and satisfaction in obtaining the required scientific competencies from the proposed laboratory.

“…1 2 (36) where K is called state-feedback gain. The sampling time for this experiment is T = 10 s ms, and the Luengenerger observer with its poles in −20 rad/s is used to compute the motor velocity.…”

“…This pole-placement design involves the calculation of the gain vector K in (36) to achieve the desired response of q. Note that this design is possible since the state-space model is completely controllable [34], which means that any initial state x(0) can be transferred to another state by means of an unconstrained control signal u.…”

“…A virtual lab permits developing simulations on the web, whereas a remote laboratory contains user interfaces and web cameras for accessing a remote experimental platform using the internet. The control of servomechanisms via VRL can be found in studies by Baltayan and colleagues [5,27,28,36,46]. Moreover, it has been reported that the VRL provides compelling learning experiences as the traditional hands-on labs.…”

Enhancing the student experience in pre‐ and mid‐COVID‐19 pandemic period by upgrading the power electronics laboratory practice curriculum

“…With the aim of offering at least some "practical" experience, in the last decades, large efforts have been put into designing effective remote, virtual, and even augmented virtual reality laboratories [7,22,36,47,59].…”
