“…Rather than optimizing position tracking, the paper's target is proving that our electromagnetic set-up behaves as desired even without using advanced control algorithms such as those for levitation recalled in the introduction [12,18,24,26]. Thus, we have deliberately kept the control design simple.…”

“…Electromagnetic actuation finds application in many engineering sectors since its driving magnetic field can easily and safely propagate through many materials and reach confined spaces. These unique features make this actuation form well-suited for multiple applications broadly related to robotics, such as electromagnetic actuation for image stabilization [1], minimally invasive microrobots for microsurgery [2][3][4][5][6][7][8], targeted drug delivery inside the human body [9,10] or early screening and cancer treatment [11], magnetic levitation (e.g., vertical motion of a ball [12]) and general motion control of ferromagnetic elements (e.g., planar steering of a ferrofluid drop [13]).…”

“…Typical techniques are complex due to the strong nonlinearities of magnetic levitating systems. They involve neural networks [18], feedback linearization [12,24], model predictive control [25], or adaptive sliding mode control [26]. These controllers require the measurement of the actuated object's position with a fast enough sampling time.…”

Electromagnetic actuation can support many fields of technology, such as robotics or biomedical applications. In this context, fully understanding the system behavior and proposing a low-cost package for feedback control is challenging. Modeling the electromagnetic force is particularly tricky because it is a nonlinear function of the actuated object’s position and coil’s current. Measuring in real time the position of the actuated object with the precision required for accurate motion control is also nontrivial. In this study, we propose a novel, cost-effective electromagnetic set-up to achieve position control via visual feedback. We actuate vertically and under different experimental conditions a 10 mm diameter steel ball hanging on a low-stiffness spring, demonstrating good tracking performance (the position error remains within ±0.5 mm with a negligible phase delay in the best scenarios). The experimental results confirm the feasibility of the proposed set-up, which is characterized by minimum complexity and realized with off-the-shelf and cost-effective components. For these reasons, such a contribution helps to understand and apply electromagnetic actuation even further.
