“…Additionally supported by experimental data, we show how ineffective the classical PID control is, thus confirming other investigations [11,17]. In [23], the authors use a position sensor, like us, but also a current sensor, increasing the cost. Moreover, from a control design point of view, using only the Hall effect sensor position is a challenge that has not yet been solved.…”

“…The proposed control law aims to enable the system output d to track the ideal output x re f under a semi-active approach. This means that the control is only activated in one direction, opposite to gravitational force, introducing a challenge control design, in contrast with, for instance, [14,18,23,[30][31][32], where the active approach is employed. Moreover, the maximum voltage is stated at 5 V; however, in the literature, its maximum is usually 12 V [19].…”

“…This experiment suggested a positive learning experience from the involved students [21,22]. It seems this educational experiment has motivated other researchers to pursue similar investigations, striving to construct their own low-cost magnetic levitation systems [23][24][25]. This paper's main contribution is to show how to construct a novel low-cost magnetic levitation system for educational purposes.…”

This paper describes how to construct a low-cost magnetic levitation system (MagLev). The MagLev has been intensively used in engineering education, allowing instructors and students to learn through hands-on experiences of essential concepts, such as electronics, electromagnetism, and control systems. Built from scratch, the MagLev depends only on simple, low-cost components readily available on the market. In addition to showing how to construct the MagLev, this paper presents a semi-active control strategy that seems novel when applied to the MagLev. Experiments performed in the laboratory provide comparisons of the proposed control scheme with the classical PID control. The corresponding real-time experiments illustrate both the effectiveness of the approach and the potential of the MagLev for education.

“…The software is available in a freeware variant for simple designs such as the MagnetoShield and has a relatively gentle learning curve. To make our proposed reference hardware truly open-source, the circuit design with the final PCB is downloadable in an editable format, along with Gerber files ready for immediate manufacturing [ 17 ].…”

This article presents an open-source device illustrating the well-known magnetic levitation experiment. The uniqueness of this particular device lies in its exceptionally small dimensions, affordability and availability, which makes it a perfect design for take-home experiments for education but it can also serve as a referential design for testing various control algorithms in research. In addition, this paper provides a comprehensive hardware design for reproducibility along with the detailed derivation of the mathematical model, system identification and validation. Moreover, the introduced hardware comes with an easy-to-use open-source application programming interface in C/C++ for the Arduino IDE, Simulink and CircuitPython. REXYGEN, another environment similar to Simulink, had also been used to demonstrate the capabilities of the MagnetoShield.

Stabilization of two-dimensional nonlinear systems through barrier-function-based integral sliding-mode control: application to a magnetic levitation system

et al. 2022

The sliding-mode control (SMC) has been used successfully to stabilize nonlinear systems, yet a side effect of SMC is chattering, an undesired phenomenon. Researchers have then introduced the so-called 'integral-type approach' to diminish chattering. Additional studies have shown that SMC with the so-called 'barrier function' can drive the system state to a region close to the origin. The main contribution of this paper is to join both setups in the context of SMC, i.e., integral term and barrier function. We show that SMC with both integral term and barrier function can be used to track any given trajectory while ensuring both stability and chattering-free performance. The potential of this novel control for applications is illustrated through real-time experiments performed on a magnetic levitation system.Keywords Nonlinear control • integral sliding-mode control • barrier function • magnetic levitation system.
