Hyperloop is a proposed high-speed surface mode of passenger and freight transport that has gained much visibility in recent years. Since its introduction in modern form in 2013, progress on Hyperloop has been thriving, with several companies involved in research and development of Hyperloop systems and subsystems. Some of them have planned testing tracks in Europe, anticipating what could be the start of commercial routes. Nevertheless, there are concerns that need to be addressed regarding the safety and serviceability performance, and further steps are necessary for the standardization and certification of the system. This study leverages the state of play of Hyperloop development, identifies issues and challenges from a European perspective, and provides policy insights towards testing and commercialization. To this end, it follows a two-tier approach that (i) addresses safety concerns related to the implementation of Hyperloop as a key enabler of the proposed technology and (ii) analyses Hyperloop technology developments using a triple-helix innovation approach, using a structured methodology based on consolidated data sources (i.e., the Scopus database of peer-reviewed literature and the Patstat patent database). The performed analyses highlight the significant amount of research and patent activity on several aspects of Hyperloop, while the mapping of activities carried out by industry in Europe, as well as from European Services, highlights the progress made towards the future Hyperloop implementation in Europe. Altogether, these findings provide factual information regarding the necessary research, policy, and industry steps taken so far that can help bring Hyperloop into the market. To the authors’ knowledge this represents a very systematic and extensive literature review on Hyperloop’s scientific and technological developments.

<span>A magnetic levitation system (MLS) is a complex nonlinear system that requires an electromagnetic force to levitate an object in the air. The electromagnetic field is extremely sensitive to noise which can cause the acceleration on the spherical object, leading it to move into the unbalanced region. This paper presents a comparative assessment of controllers for the magnetic levitation system using proportional integral derivative (PID) controller based optimal tuning. The analysis was started by deriving the mathematical model followed by the implementation of radial basis function neural network (<a name="_Hlk93327650"></a>RBFNN) based metamodel. The optimal tuning of the PID controller has offered better transient responses with the improvement of overshoot and the rise time as compared to the standard optimization methods. It is more robust and tolerant as compared to gradient descent method. The simulation output using the radial basis based metamodel approach showed an overshoot of 9.34% and rise time of 9.84 ms, which are better than the gradient descent (GD) and conventional PID methods. For the verification purpose, a Simscape model has been developed which mimic the real model. It was found that the model has produced about similar performance as what has been obtained from the MATLAB simulation.</span>

“…Although certainly beyond imagination, the selection of a near-vacuum tube as the driving environment can reduce the air resistance dramatically [9,10]. EDS levitation in the systems can achieve stable levitation without control, eliminating unnecessary driving friction [11,12]. The linear motor for propulsion is one of the key elements that utilizes highcapacity power from the stator installed in the tube guideway.…”

Development of the Reduced-Scale Vehicle Model for the Dynamic Characteristic Analysis of the Hyperloop

This study addresses the Hyperloop characterized by a capsule-type vehicle, superconducting electrodynamic suspension (SC-EDS) levitation, and driving in a near-vacuum tube. Because the Hyperloop is different from conventional transportation, various considerations are required in the vehicle-design stage. Particularly, pre-investigation of the vehicle dynamic characteristics is essential because of the close relationship among the vehicle design parameters, such as size, weight, and suspensions. Accordingly, a 1/10 scale Hyperloop vehicle system model, enabling the analysis of dynamic motions in the vertical and lateral directions, was developed. The reduced-scale model is composed of bogies operated by Stewart platforms, secondary suspension units, and a car body. To realize the bogie motion, an operation algorithm reflecting the external disturbance, SC-EDS levitation, and interaction between the bogie and car body, was applied to the Stewart platform. Flexible rubber springs were used in the secondary suspension unit to enable dynamic characteristic analysis of the vertical and lateral motion. Results of the verification tests were compared with simulation results to examine the fitness of the developed model. The results showed that the developed reduced-scale model could successfully represent the complete dynamic characteristics, owing to the enhanced precision of the Stewart platform and the secondary suspension allowing biaxial motions.
